>>22245046Everything is unnecessary. The question is: what is it useful for?
If your answer is "nothing", then you're wrong. I don't say megas were the only possible new mechanic, but they are a new mechanic. This mechanic is interesting mainly because of type change (sadly, that's not really exploited) and of ability change (THAT is exploited) during a fight. Also, in some instances, megas are interesting because there are several possible builds (with or without mega, or even with X mega or Y mega), so megas "mask" your true pokemon to the opponent.
You probably already know this. But these facts make megas useful and interesting, even if some other changes instead could have been better.
