It all depends, this game is meant to be p2w, but you don't have to be the best or top 10 to enjoy the game. The best part is being smart and making teams that are enjoyable and fun. Even if you lose more often than winning, the game is fun regardless. The game can get boring so be careful if you spend.
Overall, earlier servers are better as the later servers already request for merge. This is to be expected and you may be waiting weeks to months for a merge, so be careful on where you go. Hope this helps!
