I am playing the Arena Master server. I have just encountered a lvl 52 party with exacty the same heroes that I have, but at lvl 57. I lost to this party within 10 seconds. Within this time, all opponents had used their Ultimate and I was down (actually: I lost Elric within 4 seconds, and Zem within 7). The party has Elric, Zem, Jasmine, Taurus and Tashi. I don't believe this can be done in a fair way. All my heroes have their abilities maxed out, ar 4-5 stars, have their maximum fusions and have at least some items enchanted. They were all on 100% health.
Anyone any idea how this could come about? Could this be cheating, or am I missing something?
