So I got Rogue, loving her, first serious 60 (cyclops being first 60 at all, you can probably guess why)
the build I have currently, the Mystic Mayhem event rather helped XD.
the rotation is to throw up Lawyer Up, keep it going with Volcanic Eruption, try to keep Ragin' up as much as possible, and stick on the boss with swooping flames and solar strike. Signature is for energy regeneration or big aoe needs, and gloves off to burst damage more or heal.
the 'weak' powers (or ones I'm at least not sure on) are Mechanical Genius, Demonic Barrier, and Illusionary Projection. Genius I'm not sure if my build 'needs' or not, Barrier I find myself seldom using but unsure what to replace it with, and and Illusionary is mostly 'because why not summons when I reposition'. I should probably swap it for Sinister's dash for the energy stacking, but haven't gotten around to it yet.
