I'm using him more often now when we run a two tank comp and he really can clear a point pretty quick especially if you ult in on everyone.

Bastion can be a pain when not dealt with properly, you just need a team to know how to switch. And if he focus you when you jump in they need to burn him up. You may die but at least you don't have to worry about him for awhile longer, then your team just has to not let him set up again.
