with SOOOOOO many "thats total bullshit" moments in xcom2 how do you guys play ironman

Basically the title. I reload every few mission because of an LOS bug, weird secondary explosion that had no warning signs at all, etc. on high difficulty, lost with no labels over their head to show which is a dasher and which isnt, accidentally clicking the wrong place at the last split second with a grenade it goes on and on.

ALSO edit: Im still learning WOTC, so not knowing that the assasin just ran through 5 overwatches without triggering a single one, a dead purifier blowing up and killing 3 of my guys the first time...sorry im reloading that shit lol
