Nostalrius Begins - Quality wow vanilla realm (1.12)

So I'm in the process of planning my PvP Mage's 60 spec (17/34), and although I have the Frost talents down, I am wondering whether or not to put 2 points into Arcane Focus to cap my hit chance for sheeping in PvP. I didn't PvP on live until well into TBC, so I'm not sure how easy it is to find hit gear at 60 without raiding or having acess to r10+ gear.

And if it's not worth it, is Magic Absorption any good?

Go for the +hit.

The hit really comes in handy with counterspell more than with polymorph in my opinion. It's not 'necessary', but why wouldn't you?

2/2 Arcane Subtlety
5/5 Arcane Focus
5/5 Clearcasting
2/2 Dampen Magic
1/1 Arcane Resilience
2/2 Imp CS

I'm listing that because I'm not sure why you'd deviate from that lineup unless you'd really like to have Magic Absorption; I'm not sure where else your talent points should go other than Arcane Focus.

For a strict PvP build, 5/5 Arc Focus is pointless, since it overcaps you by 7%, even with no spell hit.

I'd take 2/5, tops (assuming no spell hit on gear) unless you also raid a fair bit.
