Hello, first post here and I was wondering which 4 stars are the best to level up. I currently have way too many 4 stars than I know what to do with so if I happen to have some of the stronger ones I'll start leveling those and sell the rest. If you'd like me to put together a list of all my 4 stars I'd be happy to do that as well. There are just a lot of them so I don't want to waste time typing a list if it's unnecessary. Thanks!
