The only Bastion main I had a game with was absolutely awful. They had 59 hours on bastion, a couple of hours on reaper and a few hours on torb. We had a comp match on Numbani with this person, knowing they wouldn't switch to something more useful my mate and I went Rein and Mercy to work around the Bastion the best we could. I managed to convince them to take high ground but they kept going out of sentry mode waaaaaay too much and they got nothing done the whole match. They weren't shooting in recon mode, they weren't holding positions, didnt use self heal at all (solely relying on me as solo healer, and I was healing them alot and rezzed them quite a few times as well). Honestly the worst experience. If you're going to main Bastion at least try and be useful when your team is working around you
