Err, yeah, slightly belated response.
The going going any faster?
Rimestrike's a good base, if you want a melee sorc.
Storm Minion & Skylord are great, once you have some points in them.
Kinetic Consumption is (still) excellent.
(Combo the two for bonus points, Minions for damage, KC for CC.)
There are a bunch of skills that become very good later on, but don't start out too amazing.
i.e. the crafting skills and Thunder Storm.
I'd try them on a second/third character.
And, as stated, vanilla builds should still work.
Need anything beyond that?
