Old player here! And I think moving power events is a really good idea! Having so much going on at once was probably part of the reason I got so burnt out, and moving it to every two months would make things much more manageable for both mods and players.

It would also be good to spread out the powers, so that people can get used to one power before having a second one pushed on them. I actually stopped giving Yuuya powers toward the end, both because I thought he would be getting too much too quick, and because he hadn't participated in the events.
