Bad Motovator

In the Tier 4 (I think) of the marquee battle this ability was off cooldown right from the start. Now marquee is unavailable but it still possible to do it in the Coliseum given right conditions. Yesterday I fought level 4 boss with lvl 47-48 droid (spend some crystals to get it there). The rest of the team was less than 40 and was wiped in the end but droid lasted enough to fire off Bad Motivator 2 or 3 times on auto. 

So, the key is to have the droid level higher than Coliseum boss and let the other team die (or don't use it at all, or just take some leader which boosts survivability).  You experience may wary but at least you can try.
