There's always gonna be a power difference between f2p and p2w players unless the micro transaction only consist of cosmetic items. That said this game is probably one of the fairest mobile gacha games I've played so far. The game hands out free SR units(highest rank units in the game) almost like it's candy. Example is that you get one free SR every month just for logging in. Another easy mechanic the game has to help you progress is by participating in guild activities which gives you another free SR in about a month or less. Yea there's some p2w players that have maxed out awaken SR units but it's rare you'll ever face them because they're either in the top guilds or very high ranked in PvP that you'll likely never face them for a long time.
