I think the perk system and the game generally have to be rebalanced now with all the dlcs. Many weapons and tactical opportunities are useless.
The only reliable tactics to beat all the game’s challenges is Berserk+Killing Frenzy for everyone to maximise the damage and wait for the enemy to come.
Since unique armors sirvive the damage after battles as loot, dagger build becomes useless while being very situative and demanding itself.
Indomitable perk is OP especially in combination with Adrenalin. I think Indomitable shouldn’t exist in the perk tree at least for Expert difficulty or should be reworked somehow.
