Agree sir. The updates of every new version of a ninja release is equals another obsolete ninjas that will not be used making it hard to enjoy the game because the meta change so quick many will not be able to catch up and think it's a waste of time to collect that ninja frags if the updates always releasing new version of ninjas which is more powerful than the past version of that ninjas. Revised skills or add another skills in their breakthrough so they will not be left out when there is a new strong ninjas will be release
