Yeah, these are all mobs that do high damage on account of them being telegraphed and them not occuring in packs. All of their big damaging attacks are easy to avoid if you’re not of the opinion that dps builds shouldn’t have to move out of the way of incoming damage.
There’s already a thread on this.
Some of them are a bit frustrating (Avalanche tracking you when its a cast skill not a channel & the telegraphs for the necrotic XXX flesh guys appearing in mid air), but they’re all easy to avoid.
This is the only death penalty there is in the game. I don’t think it’s unreasonable.
The ones you listed (except possibly the Avalanche ones) are all champions.
Not with 1.3k hp its not. You get oneshot because you didn’t move out of the way of a high damage telegraphed ability and you dont have enough hp.
Also well telegraphed with the possible exception of some combinations (phys/poison spires on dark tilesets, cold spires on snow tilesets).
Or, you know, running out of the way. You don’t need a movement skill unless you’re surrounded by mobs at which point, if you’re in a spire mono, why did you let that happen?
