Veena if you're looking at frost I'd probably go for
0/0/52 if you're going for single target levelling (and I think aoe grinding hasn't really been viable for a while - and it's not great for outland).
It includes quite a few mana reduction talents to reduce down time, and brain freeze (instant fireball) as that seems to proc quite a lot and would make for a good finisher (it's mana free so you'll start to regen mana faster). Main focus if this spec is freezing things (survivability) and then critting the hell out of them (remember to do a frostbolt and then icelance straight after on frozen targets for an increased chance to crit with both).
Iffy talents - I picked up Winter's Chill, but not sure how useful it will be in solo play (as there's less time to get it to stack), so you might consider dropping that. I've also taken frost channelling, but if you don't have mana issues I'd drop this for something else.
I've skipped Fingers of Frost becauese I read that it doens't stack with Frostbite, but I'll admit I don't know how that is worked out at the moment, so you might like to pick that up and see if it leads to even more 'frozen' targets and so more crit chance.
Now onto what I was actually planning to post about (I really need to learn to be more concise), I'm currently running a kooky frost/fire spec (
0/8/53) with points in World in Flames. Would I be better off putting those 3 points in incinerate for added damage to my brain freeze fireballs? I was surprised at how often BF procced, but haven't got around to testing if it's actually worth casting the fireballs yet, WiF is good for aoe (which is most trash at the moment), but I can't decide which will be better overall for damage.
Edit: Shatter =/= Frostbite
My excuse is that I levelled as an aoe spec so didn't really have experience of either of those talents (and I've still never had a build with Frostbite in).
