Just to clarify: have we determined which monsters are affected by this HP bloat? From what I remember from my playthroughs is that Bugbears, Ogres , Minotaurs had same HP as in Monster Manual.
They have upped goblin's HP for sure. But.. are there more?
It would make this discussion more precise.
Spiders too. But considering how goblins are prevelant, "just goblins" is like "just 40% of enemies on act 1/EA".
