On T2 I was hit by an 18k distributed attack on my RK. Not sure why I get one-shotted when a hunter standing right next to me goes unscathed. Other times I've seen 7-9k which isn't quite one-shot for me but was still brutal with inferno. Other times I see 1200-3k which is when more people are hit by it. I never looked if the attack could be b/p/e but I kinda doubt it. I only seen the mechanic out of wack on T2 runs.
