Basically i came up with a 65/3/3
(derived from your spec) I took out Arc Fort because 150% of your int as armor isnt alot since you dont have a huge mana pool. I moved the talents into Arc focus so i dont have to gem for hit and focus on gemming for haste or w/e i need.
And lastly i took Frostbite for the pesky melee fights (when im useing frost armor)
Edit:forgot link to build
IMO, if you want to put 3 points in frost, i would put them into Ice Floes.. 5 minutes is an awfully long cooldown on ice block when that rogue simply will not get off of your junk. (but again, that's personal preference).
Anyway, you asked what my tactics are in BGs.. and that's really hard to say.. it's hard to have a "tactic" for BGs (and to be perfectly honest, i haven't pvp'ed much in a little while). I tend to run around with a DK/Disc priest in my guild and I find that's a pretty fun combination to work with. We haven't brought the comp to arenas yet since the DK is taking a vacation from WoW (which is part of the reason i'm taking a break from pvp). More often than not, either the priest is focused, or the DK is focused, leaving me free and clear to put slow on my target, and nuke the living @#$! out of them before they realize just how bad i'm owning them.
I made a macro linking arcane power and arcane blast together, so i just hit that button and start casting away till missile barrage procs. Usually by the time it does proc, whomever i'm attacking will turn his attention to me, so i'll refresh slow on him, blink away, and let loose with it. between that and whatever damage the DK has been doing to him, he usually doesn't live long.
