Random new year update:
1. Was irritated by how slow + careful i have to play my character to safely level up each time (magic map T5 only atm), thus tried to start a new character which is skeleton necro, but turned out that i just cant get into playing multiple character each season. Probably will play slowly, 1 act per day. Stopped immediately after finishing act 1 despite it was only like several minute.
2. After several long grinding for metamorph encounter with 100% MF, i got several unique that properly upgrade my power level which made me able to beat uber izaro safely (i kept getting 1 shot by him, so i wear cdwt + enfeeble with rearguard for some block)
3. I rewired more skill points from focusing physical -> fire conversion (with a lot of strength), i finally got decent DPS that made me easier to clean up T8. Atm im on the way to deciding either i from switching from chieftain to slayer (faster farming) or pathfinder (better boss capability), regardless i need to rewired about 30 more skill points to go crit / staying at ranger tree.
4. Bloody Drox with area level of 75 (region with 1 watchstone) is FREAKING TANKY. My gosh, i always ran out of flask charges and can only damage him to 1/4 hp. Always become almost perma-invincible after that. At this point, i think im probably will just skip him until i can clear T12 map or something.
Judging from my previous PoE character, it seem like i tend to quit the game around level 90, this league is kinda like less irritating because there are more content to tackle rather than MAP MAP MAP MAP MAP MAP MAP. But still, some content are not rewarding enough though, making it hard to play SSF as i wanted.
EDITED 3 hours after first posted
1. Make a big decision to go for pathfinder + elementalist as my final build. I converted all my available currency for regrets which yield about 50 regrets to play around with (i dont care much since i dont play standard or 2nd character). Turned out it was a good decision as i finally managed to tackle long boss fight, specifically conqueror boss. I finally killed drox, although i was downed to last portal.
2. Im gonna admit that this is first time i feel like i playing PoE like is supposed to. I used to play many ARPG spamming potions and taking unnecessary risk which lead to a lot of death. Despite have 3 life flask, it was useless since im not fully utilize from pack to pack, mostly used only for boss fight. Thus with new pathfinder ascendancy, i can keep playing spamming pots, without needing to worry about flask charges.
3. Additionally, im now playing with balancing my skill points in the tree. It still my goal to get 4.5k life as i kept getting 1 shot on certain meta boss despite having some armor + enfeeble + arctic armor, hopefully i can then tackle atziri + other endgame content.
