In FPS games you get one-shotted all the time
In all seriousness i don't think that with 800k health pools ppl will continue to get one shotted specially since crit damage is no longer as high as in vanilla.
How isn't it it as high? We only lost one barb passive....
Also... we have 3k dps x 100 (main stat) x 40 (skill) (12M) base damage even before crits.
