I think the frozen wasteland is likely to be one of those dungeons for newer players the devs were talking about. The achievement rewards seem to suggest so anyway.

I had an idea for an arena event that a lot of players may not like but to me would create a nice change from the usual. A week where arena is limited to natural 4* characters or less only (if doable). Imagine not seeing a sea of awakened characters and endless gambler eddies in the defense list. Would provide a nice change up and get players to think outside the box for a week I reckon.

Okay queue responses as to why that would be a shit idea in 3, 2, 1, go... lol
