its more a question about your goal in this game ... If you focus on having fun, definitly you go for the ninjas xD If you go for competition, just stop the game, People like Armand will spent a lot money to have the new ninjas which are always broken af.

Im a low spender (just the medal for naruto chakra) and im number one in my server, but since they merge the pvp event, im not interresed in pvp event at all now. Its more based on who got the best wallet, then the best strat. So yeah if you focus on pvp event just stop this game xD
