So many mobile games are comming out with real time pvp why not this 1? They could send game alert to our phones 5min befor we fight. If you get on then you can do your battle yourself. If not on in 5min then battle is auto. Go until you lose. Prize is based on how far you get. There would be 1 rank 1 and rank 2 prizes. Then 2 rank 3. 4 rank 4. 8 rank 5 and so on. Have it were you still need to spend ally points to re-use toons.
Just a rough idea.
