You can disable automatic updates on Steam for PoE2 and then only launch the game without running Steam to avoid updating it.
Also you will probably beat the game before the rebalance if you try.
i highly doubt it - i already am 35 hours in it and I am only exploring Nekataka. I like to really take my time with those games and read every single think I find. Helps me concentrate better in other things I do, strangely enough..
So does Path of the Damned actually make it a bit of a challenge? Veteran was so easy there was only a couple of fights I had to even think about.
I am below level 10 so for me it is a challenge. Others in this thread say it gets easier from there. In any case it at least forces me to make choices as to what abilities to use and how to place my party and who to attack first. Veteran started to be like "left-click to attack and watch what happens till you win"
