I think DaS2 has other flaws (mostly in the level design being super gamey and the animations being very floaty which are issues unique to it in the series) but it's hilarious seeing how many people get filtered by the concept of 'divide and conquer'.
Also something I've noticed as a PvPfag is how many people expect to INSTANTLY chug Estus. You'll fight guys in the Belfries, well past the point where they should have learned, and they'll roll back once or run backwards for half a second and start chugging in front of you. It's absurd how much the later entries have encouraged reaction based rollslop instead of actually thinking your actions through
