I've focused on Amazon this ladder (currently #2 amazon). The class has several serious issues that should probably be looked at.
General class breakdown:
Currently, Amazon has two playable specs. Specifically, hammerzon and bloodzon. These two specs are so far out of line with the rest of the class tree that it is nearly impossible to play anything else.
Curare has no place in the Amazon tree anymore. None of the specs scale with poison damage, and we have no skills that are good at applying it. Almost every amazon attack relies on multiple hits (bows and javs) or provide massive physical scaling (jav and spear).
War Spirit was hit too heavily by the crushing blow to bosses change. It was already a mediocre skill to invest in, but the reduction in the number of procs on gear and removal of crushing blow from bosses hit this skill on both sides. I still put a point into it, but mainly out of stubbornness rather than utility. This really needs some love.
Hammerzon, in particular, is a massive outlier in all regards except boss killing. It easily boasts 75% block with 350k defense with almost no gear. In addition, hammers deal full physical damage at 150% WDM, which is an insane outlier. This results in 5% leech full healing a 16k hp Zon in 2-3 hammers. Nothing else in the Zon tree comes close to this. Furthermore, because this is a WDM scaling skill (attack), it only requires a single stat point, allowing the Hammerzon to max defensive options with no tradeoffs. Personally, at lvl 125 I was able to easily solo 8-man fauntz with only a single (fairly common) SU scepter (legion). Furthermore, Asterism is way out of line in terms of power. It makes max block investment easy, provides flat damage for insane scaling, as well as enormous enhanced defense (with max thundercrack).
Bloodzon, typically Magic Missile Zon, boasts incredible boss killing damage and very good clear, but lacks the total invulnerability of hammerzon. This build is more "balanced" as it scales well with gear and has a few end-game options. If anything, this playstyle could use more support in the SU and SSU department, but since physical/magic spells are the name of the game (neutraldin as well), things are probably okay here.
Javazon is alright, but currently does too little damage compared to other builds. It is a mid-tier farmer, boss killer, and tank. The class can be played, but relies heavily on Danmaku, an SSU shield, and even then is clunky and underwhelming. The full strength of javelins come from the free DR and regen of Moonbeam combined with the physical damage and deadly strike from Moon Queen. However, heavy physical scaling w Moon Queen is under-supported in the SU an SSU slot--heartseeker looks to be the best of the bunch but is not great. The SSU maiden javelin, Titan's Revenge, focuses heavily on fairy ring, which suffers from elemental damage scaling problems, reliance on corpse positioning (even with sacrifice), and high mana cost. The new level cap actually makes it difficult to reach max block on javelins even while using a +1 amazon shield (Danmaku). Even with full perfect amethysts, Javelin users are pushed into 2+ pieces of abandoned crafted gear with additional % dex on jewelery at higher levels. This can be mitigated using specific uniques/runewords for additional max block chance (Shaheeda), but further prevents an already mediocre damage spec from gearing into full damage.
Traditionally, javazon is a heavy proc-based class using Danmaku + other javelin/arrow/knife procs to deal additional damage. The overall proc reduction is very noticable for javazonIn addition, ricochet's base WDM of 60% feels very low for a skill that only hits a single target one time (compare to iron spiral or deatgaze).
Spearzon is incredibly fun to play, but has some clunky mechanics that hold it back. Pounce is a classic skill and still feels great to play. However, the rest of the spear tree is currently just a bit meh. The blood globe mechanic performs very poorly on the often-laggy MedianXL servers. Overall, spearazon is fairly alright as a farming spec and is worth playing around with. The fact that the single target skill, hyena, does poison damage is a fairly big detractor, but amazon has poor single target overall outside of Magic Missiles. Note: I have spent less time testing spearazon than other specs.
Bowazon is currently in a very bad place. Beyond core mecahnical problems discussed below, it suffers heavily from multiple Sigma changes. First, the removal of aggressive cheap reanimates (skeletons) removes its only layer of defense. Second, the skills no longer out-range mobs--the larger resolution means you're constantly getting hit from out of range. Third, the tiering of endgame zones means that you cannot focus on the few zones where bowazon is alright (Teganze and Duncraig). Fourth, the new TUs and SUs provide no way for bows to compete in the mid to late game. Fifth, the removal of crushing blow from bosses completely neutered Bow single target.
At a high level, bowazons suffer from poor damage, zero survivability/no sustain, and low range.
Damage: Bowazons are intended to rely on heavy raidbow damage (+magic) through dragonlore. However, elemental attack damage currently scales very poorly. It is only scaled through -res, but -all res is--understandably--rare. Thus, bows deal very very poor damage throughout Hell difficulty. Even with high-end gear (Rainbow Maiden, Athula's Wrath, Bad Mood ring) rainbow damage fares poorly when compared to pure physical bow damage. The base damage from a 350 avg damage per hit bow (of which there are several) when scaled by dex (often 800% damage) provides as much or more damage than massive flat added. Furthermore, dragonlore is currently very undertuned compared to other amazon tree passives. Since it only adds maximum damage, the actually added damage by Dragonlore is often only half the tooltip (going from 1-1 fire damage to 1-1000 fire damage only adds 500 average damage). Finally the WDM multiplier on bow skills are all low, with Wyrmshot and Barrage further reducing your already unscalable flat elemental damage.
Zero Survivability/No Sustain: Due to the elemental damage focus of bow skills, leech is not a viable method of survivability, even with the large HP pool from Paragon. As a result, many bowazons have selected Spirit of Vengeance in order to provide some meat shields. At a minimum, dragonlore or ecstatic frenzy could provide life on stirking per base levels so that bowazons don't have to hit a health potion every 6 seconds (if they're alive).
Low Range: The skills in the bow tree are just bad at delivering damage, especially in the increased resolution world of Median Sigma. Unlike bow druid and xbow necro, bowazon's skills are very short range (barrage), slow and short range (wyrmshot) or clunky and difficult to use in most situations (phalanx). The new rapid wyrmshot skill from the SU askarbydd is so much better than any core bow skill that it makes any other bow feel useless.
TLDR: Amazon has 1-2 OP specs and a lot of problems with its tree as a whole. Many of the sigma changes have negative side effects on the Amazon attack trees and the various tree passives are not well balanced against each other. Please help Bowazon!
