Since the last arena event I still have Coalgiver defense. Arena is not much fun to play since years, but recently it got even worse. But even down in the ranks (~#700), several moonboys, fully awakened liliths + lucifers are around, but most of the other teams are by far more fun to play (and/or easy for autoplay).
Actually I need the ~200 Ironite I usually get per week from Arena and I think the more easy matches won't compensate with the random chance of 1 or 2 Ironite per match. So I might need to return to a normal defense, which would also mean I need to open my moonchild soul to join the party? I really miss the good old days in the beginning of the Arena. The character's skills and talismans just became too powerful in my perspective to run Arena as it was designed years ago. The change in reward system was strange, as rank and points don't fit. Some sort of devisions, power limits (related to characters/talis) and stuff like this would be cool. But I guess there is no time to work on such ideas. And one other big obstacle: Balance is simply unwanted in the freemium world. Same might be true for some bugfixes.
