wait till we are getting more stuff .. water and wind have theyr moment to shine .... tho it is not now!
example wind
we dont have the ninjas that made wind strong on older versions of the game ( like playboy sasuke) and the thing is ...the secound you gonna have a chance to get those ninjas ... the meta will change entirely.
Just wait till things get added ... we are 2 years behind the game version taht is the most ahead ... so we all will have to wait :)
