So, the monsters I mostly hate in this game are
-those flyes from act2 oasis and further
-invisible snakes with spear (reference: before belial)
-lacuni huntress (those animals jumping on you and throwing grenades - act2)
-monster before Maghda, transforming humans, coming from offscreen and slap you to death
-icy quillback "spiting" with speed of light - semi-imposible to evade
and worst of it, those listed above elite style.
I am already too frustrated to continue, I had no fun today.
