Just to add to that, my thief rogue / gloomstalker / fighter with sharpshooter is an absolute beast and has way over 70% chance to hit on all enemies, most of the time it's 80-90%. With sharpshooter on all the time.
its not 95%... and 70% vs bosses is shity accuary
you do more dps with 95 acc without sharpshooter than with 70% acc with it
simple math miss = 0 dmg 0 crit
hiting mean dmg even is less
