Kind of in the same spot, a bit burned out, so I';m concentrating on writing AE missions (well, OK, on one that just won't ever finish). But before that, it was anything with Savage Melee, that's just loads of fun if you take at least one more "combat TP" power like Shield Charge or Spring Jump or whatever it's called.
I'm finding that leveling a new character just doesn't have the same zing, and for various reasons, going back to my old 50s also is missing it. Still, I can log into any of them and have a good time for like an hour or two, so there's still that. Just nothing feels necessary right now.
