When you are going to do something against those cheaters? Last fuse tournament rank 1 player had 233M VP from one tournament only (IOS). Now he is rank 1 in overall ranking too. Just from one tournament. That's rediculous. Guild Vietlegends are cheater too. They have a trick to get free gems and know about a bug to kill hellboy 2 with one hit.
They destroy the game for player who try to give their best on legal way.
