I have mindblowing suggestion
1-First of all, it would be nice if we can change our usernames and clan names.
2- We should be able to choose our opponents in the clan war ( but not rejecting them because wars aren't invitations :D) instead of being randomly picked against an opponnet.
3- I know that we can't open the game while being attacked, but you should replace that with the ability of viewing that player attack you in real time .
4- And you should add filters while searching for opponnents : for example i would like an enemie who has a loot between 100,00 and 200,000.
5- And finally, you should be able, after selecting the row of walls, to upgrade them all in the same time.
