Riftbeast-Champions alwys kill me instantly... but why?

Actually running 370 Corruption with the Judgement Pala , Resis are maxxed (except Void at 72%), critiimmun, 3500 Life and 1000 Ward. Bosses and Harbingers are a Breeze and everything is fine. And then i try the Riftbeast-Champions. First Try went ok so i set a whole Area with these Echoes. But in Echo 2 i can´t survive. Always got oneshot. And i don´t get it. And since it seems they don´t show you anymore what killed you i´m confused. Standing in my Judgement and…over. Tried 6 Times and the 3. or 4. Riftbeast always gets me. Tried to get more Life but that´s a bit hard cause my Gear is (for what i know) at this Point pretty fine.
Are they such Machines? Or am i missing something?

What do you mean? They still show the death screen that tells you how much damage you took and what killed you. There have been a few screenshots of those this season in these forums already.
