Which character were you playing as? As annoying as Tracer and Reaper are, you can handle them easier depending on your approach. Close up battles against Reaper means death (
) already. Keeping your distance from him while attacking will make it a ton easier. Tracer is just gonna fukk you up if your a slow character with that annoying zapping by she does, but get her alone. She's got like no health, so like 2-3 shots should do it. Tho they always do that time travel
after taking a couple shots tho and be gone with the quickness
But that situation you described alone is gonna be hard for anybody with a dumb/clueless squad. Ya'll should've had a sniper or 2 on deck for the Bastions. Especially if they had no healers. Put a healer with that squad tho and keep em with the Bastions in the back and yeah, they'll be pretty much invincible
