Pretty much in every game you have meta (most efficient tactic available) teams, and they are meta for a reason. Ninjas in this game are either 200$+ or few months of farming, no wonder people tend to get 1 meta team, that is either cheap or easy to get (infamous water 1010 mabui mei, since with luck u can get whole team with 70 seals) and play with it. I'd love to use something other than im currently using, but I simply dont have all required ninjas/summons and thats the problem all players (except really heavy spenders) face. Since it's pvp oriented game, it's obvious all of us want to get a working team and then focus on being stronger. Complaining about players won't change anything, it's the system's fault. That's how the game works- you either go along with it or switch games, since it won't change.
