Just curious, I don't think they ever said what was going to be in the arena. I haven't seen anything saying that it's going to be a fire fight/ survival mode, everyone has just started assuming that's what it is. For all we know it could be 2 waves of dregs followed by a servitor or something else equally disappointing. I feel like it's not going to be some survival game type unless it involves no loot. If loot is involved I would say there is no chance it will be endless waves. It's assumptions like this that create so much disappointment in this game.
