If I could have different powers in each one.
I'd like to play around with a 90s X-Men build, using only powers stolen from characters that appeared on the 90s cartoon. But I don't want to scrap my DPS-focused build to do it.
I'd also like to try the "lazy summoner" build, and a few others, but it is SO MUCH WORK to forget powers and steal/borrow new ones to try. Especially when it's a month or more between Limbo events.
I could see paying for several alt specs, if only I could have the option of different powers in each one.
Lately I hardly play Rogue at all, even though she is my all-time favorite Marvel character, because I feel so frustrated by not being able to risk forgetting powers to try new things with her. I want to play with different builds but it's just too hard.
Gaz, please increase Rogue's customization by allowing us the option of different powers in different specs!
