Feedback:
After playing Sigma some more, I've noticed several issues that were implemented, so I want to talk about those issues.
1) Sprint
Yes we have already talked about it a lot, and I'm sure you can't hear it anymore. The sprint mechanic is simply aweful. It makes you want to abuse bugs in order to free up another finger. The idea behind it (Having a Oh-Shit-Button to escape fast) might really be good, but the execution is aweful, because it feels punishing to sprint, not rewarding. One way to make it feel rewarding is for example giving the player a little visible defense boost of like 50% TCD while walking, and make walking faster again. Right now walking through Ureh is aweful. The zombies are as fast as you, so if you just keep walking you'll never get away. Or the same in Duncraig. If you just walk away as soon as you see a barrel, you won't always get away. Ofc that heavily depends on how much FWR you have, but all in all being slow is not fun. Another way would be to exchange sprint completely with a short-ranged teleport like Flash from LoL, give it no cast animation and an instantaneous effect. That way you also have an Oh-Shit-Button to get away in dire situations.
Either way, please revert that back to the original or rework this. The way it's now it's not fun, it's only tedious.
2) SU's are locked away behind a heavy level wall.
I have 142 sigs eaten. During the time I ate all those sigs, I only found 6 SU's in total. Stone Guardian, Silverhood, Lacuni Cowl, Zayl's Temptation, Quov Tsin's Talisman and Griefbringer. That's it. The rest are set items and sigs found in Torajan Jungles. Tran Athulua is now a completely trash uber. You neither find SU's nor more Uniques than you could farm in hatred by killing Mephisto. The exp in TA is also overshadowed by the new, good uber in the same level range: K3K. In K3K I found 2 SU's, many more sets and I gained lots of Exp in a shorter time. Which makes TA basically useless. So there's no good way to farm SU's until you get to Duncraig, which sucks. You have to rely on sets, and many of the sets are still not balanced or feel good to use at all. There are so many issues like Witchhunter set not having a shield, even though you devs admitted that wielding 2 weapons in D2 is bugged, or necro summon set giving lots of strength instead of useful stats.
To get to the point: You have to rely on sets, but sets aren't balanced at all. It also causes the same mistake D3 made: You force people to use sets for an upgrade (else you can only rely on RW's and elemental RW's) and SU's are locked behind Duncraig, which means you force people to get into certain builds. A Bow paladin? There's no set for that. A sword zon? No set for that either. You basically tell people: Play what everyone plays, else you won't get any progress.
Note: This is a highly hyperbolic paragraph. I do understand that you want people to also use sets of different characters, it's just that before you make people rely on sets you should fix them. That's all I want to say. And make SU's more accessible in TA because atm TA is useless.
3) Big, empty areas only artificially increase ladder duration.
There are many, many areas that were added like the Silver Spire 1 and 2, Silver City, Subterrenean Corridor, Bramwell and so on and on. While I do enjoy their looks and exploring the new stages, I do think it's only a matter of time before I'll get tired of them. Just look at WoW. When it started the player numbers exploded because everyone wanted to get to know this new world. But nowadays everyone knows every area, so it's just mindless, boring grinding to get to the max level. For a short player number boost, it's great to add new areas, but those areas are mostly completely useless connection areas that add nothing but a longer time to get to your farming zone, which means you artificially increased ladder duration because it takes a lot longer to get to the areas. Just look at Caldeum. There' no easily walkable way, you always get stuck somewhere when you walk or you have to look for a new way... if you don't have teleport there, this area is annoying, useless, boring and way too big. Couple that with the sprint mechanic and congrats you have a boring game.
Yes I've read you want to add new waypoints in the future and I'm really looking forward to this, because the way it is now, it's completely contradicting to your general philosophy.
On one hand you make the game more for casual players, lowering the difficulty in the leveling to 100 part and lowering difficulty in general. On the other hand you want them to grind more and more. So this game is now neither for casuals nor for hardcore players. What kind of players do you want to attract? You should really make up your mind about that.
