I believe the only enemy which got severely nerfed was the deathsquito, i remember that thing dealing like 100 damage early on one shotting you. They were absolutely ridiculous, you just couldn't outrun them, getting close to a plains meant you were dead. In my latest playthough, i got close to plains, saw one of them coming towards me and i knew, i was dead...... 40 damage, with lvl 3 troll armor, bit less than half my health, could even parry them with a bronze buckler, which i couldn't do before.

Also, i seem to encounter far less 1 and 2* fulings, i remember encountering them by the dozens in a few minutes, now i'm lucky to see 1 or 2 a night, mostly none.
