My main on Live was RooGirl, an MA/Regen scrapper, and I'm currently having fun recreating her. I know it's not the OP combo it used to be, but it's my fun build, with stealth and other extraneous toys.
I'm also playing a fire/fire tanker with my mom, we used to play together on Live and we're having fun with it again.
I'd like to play something completely other than melee DPS, which is what I always gravitate to in MMOs, because most of them don't have the flexibility of CoH's power system. Something that's great at soloing and would also have utility in the endgame/TFs/etc. No MM, because while they're fun, they're fiddlier than I want. I'm thinking along the lines of blaster or controller, but open to almost anything other than brutes, stalkers, tankers, etc.
I'm asking for advice largely because there are so many more powersets now, I'm kind of paralyzed by choice. So if there's a combo you particularly like, and it's a strong soloer, tell me about it. I don't need to solo AVs or crazy numbers of +2s, just a fun soloing experience. I'm also looking forward to creating a costume concept around a brand new AT/powerset. Thanks for your suggestions!
