Nice that you guys organized some sort of event, just some constructive feedback.
-It wasn't really worth doing, as there was no real reward to yield for anyone but the people that dealt the highest damage to titan.
-At one point, there was mention of "one last mob", followed by 3 more waves of 40 trash mobs that were spawned. Which comes across a little amateuristic, I don't mean this offensively.
-There was no official, 'ending' message given. It was, "Message: one last mob", followed by 3 waves of random beetles. And then everyone just waited around, wondering if it was over or not as it wasn't made very clear.
