On death effects and bugs

To get to the point on death effects and plague monster exploding...its straight Diablo TRASH!!! The monsters DEAD, he had 6 modifiers..as a melee player its hard enough getting close enough to fight it in the first place. (Bugs) First off every other time or after a movement skill like flicker my dude just stands there not stunned, has mana, not stuck, can still move and roll but he just Sits there and usually gets murdered. 300+hrs...its getting exhausting. sorry to rant.
