I pre-apologize for this, but I have to (sarcastically) rant:
Fives loses 1v1 miserably vs stunners even if he has much more HP left when the fight begins. Please nerf every toon which stuns on a basic attack. If you can't keep a stunner alive until the end, start stunning Fives at the beginning and working him down. Oh, wait, but then he's acting like a (soft-)taunting tank, so that won't work. Guess who else would crush Fives in 1v1? Any character who can resurrect the whole team. Please nerf them too. If I go 3v1 against Daka and she resurrects the team, that's just OP and not fair.
