I'm currently in an HM 50 FP with a Melee Sorc.
I'm not joking, this guy is running in and swinging his saber like a pro.
Addendum: He's also using force storm single target. Lol.
IF you are all lvl 55 or most of you, why not? I'd do that as well just for the fun of it. There is not more better chances for lvl 55 sorc to enjoy his lightsaber than lvl 50 FP.
