I've also suffered from having a team be to strong making certain content more annoying to deal with on auto. Twice this event I've lost ultimate Rahab on auto ability. This was because my subs are random himes I'm leveling but mostly because no burst build up due to killing all trash with skills. So to fix it, I just regular auto attack the entire thing and it works. I'll get hit by 1 raging overdrive but that pushes my team for a full burst which pretty much kills her after. Hasn't failed me yet.
