How to not die until Selig?
What's the trick to not die to every fart? I had the luck to find mythic Gohr's and craft a mythic Grandfather and damage is sufficient to blow everything up in one hit (once whirling for 30 seconds) in Pit 115, but any fart just instant kills me. I don't mean ground effects, I got used to avoiding them - though I still have problems with Mephisto's last phase even on T10 as something I don't understand always hits me as an instagib.
I only have 20k life, which obviously seems not enough - but am I supposed to get GA max life on every item until I then need to find new items without it if I ever find Selig? Is that really how it works? Looking at the leaderboards with the many people seemingly not having problems, they don't really have maximum life on their items, even when they don't have Selig and my items looks pretty similar.
Does Endurant Faith change that much? Couldn't find that yet.
Would be happy for confirmation I need to get a full max life gear set or what the trick is - first time playing WW barb in D4.
