The only big problem with this is when u have to update it makes u uninstall it then reinstall to get the update apart from that I find it a really good game also would ve nice when getting shards to not have the same one u have come up so often and for it to give u new ones a little more often so really just those 2 things that are annoying I've found another bad thing it's the arena it is fixed it forces u to spend a stupid amount of gems just for one fight to have a chance of winning
