Game is harder, or am i crazy? Prob crazy

Playing saltz bh with new patch. Decided to play champ, because legendary is 40/60 win loose. Usually because i dont play that often, i miss some hits and die. But in champ im better, due to reciving 2 hits and still being able to live. Buuut it seems not anymore. We held one grim, and pessant rat almost killed me with one hit.
Was it always like that?

Edit: did some testing, and maybe i’m crazy, maybe there was a bug, maybe just that specific map has one rat that kills with one blow or something.

You sure it was just a single rat?

I am fairly sure a slaverat can on legend take like 40-50% of keri waystalker/shade health in a single charged hit but it shouldnt be more than that.
