Increase the storage of T2A
I played this game for almost 2 years now without any 5* 4/55 (don't have any good 5*). So every T2A i got just went to the storage until it was full. Recently i finished act 5.4 and that leave me with SIX additional and it went to the stash.. im going to R4 rulk as i don't have any options.
Looking at this month calendar my prediction is that 2 of my t2alpha is going to be expired in the next month. Please do something about it, i'm sure that im not the only one here with this problem.
Cheers
