The game is just revolving around RNG. If you failed to pull a character because of bad RNG then you are bound to reach low on rankings forever until you get that character. This game is polluted of RNG, there is little to no skills needed at all, just rely on your luck. In a nutshell, this game is the RNG itself. Another thing is that this game is quickly turning into P2W, there's just too many and too much benefits to paying players. The game isn't balanced anymore.
