New game ?

So the Genius idea is to start a whole new game inside this one ? So you want me to upgrade new characters that I can’t use in regular game play ? Wtf ! Seriously!! So I’m supposed to spend time money and gear on basically a whole new game ? If I wanted to play a whole new game I would go to App Store and download a new game . Make sure it’s not from EA . Been playing the whole 10 years this is worst update so far . Someone needs fired over this .. 

all this time and money to upgrade my roster and I can’t use my roster in new arena ?  Can’t comprehend who thought this was a good idea ..
