Just fought qgj, lumi, gs, sid and poe against my phasma, fotp, gs, daka, han.
Sequence: qgj attacks daka, sid aoe, his gs kills my gs. Poe taunts. My daka heals but no revive. Han taunts, phasma speed down, fotp almost kills poe, their lumi hadouken han, my team goes again and manages to stun and obliterate the opposing team with no more deaths.
I waited until han was 7* max gear and hit 6* on fotp (today!) before using on arena. Even if one toons dies before han taunts, the turn meter between him and Phasma more then makes up in 4 v 5 situation.
