simple but necessary change suggestions

Ever since the akuma update, it has been way to hard to get the shards to level up characters. I've only had 4, 3star characters and i've only been able to upgrade them once or twice each in the 19 days since the update. And i have been playing alot. 

Also i dont like the animation for opening chests. It taked too long.

Cashing in extra character cards is also a hastle i wish you could cash in all at once as opposed to the current, which is one character at a time
