I wonder if I'll get banned because of Coliseum luck.

As always, when reaching the 90%+ phase in Coliseum my damage outpuut dropped to 1dmg every hit. All my debuffs were resisting and I was down to my lvl55 Partagaz and Dedra. Somehow they settled into a rotation of recovering health and protection beyond what the last remaining Zeffo Tomb Guardian at lvl 5 could inflict. 

Because the boss' damage output didn't ramp up like a rage point to say CGs usual "you're not allowed to win this" moment. I was able to weather the storm and won, slowly.

 Having little to no faith in CGs account banning from Coliseum. I'm genuinly concerned and waiting for an account ban when the AI looks at it.
