I regretted that I have spent 3-4 years on this stupid, grindy game. In the early version, this game is still somewhat tolerable, but turns into a more and more brainless game for kiddies that are prevented from playing league of legends. The "strategy" of this game is literally buying the newest character that has the most powerful stats and after the character was nerfed, rinse and repeat. This is a lazy cash grab intended for earning money, just like a majority of life service games.
