So im a gnome and im going to twink my mage!  : )
Got some ideas, and tend to keep an eye on who does well in WSG and then check them out for ideas on wowarmoury but dont see that many mages in there.

Any of you guys have any suggestions? I've been in plenty already at lvl 18 with average gear and know i can do really well at lvl 19 twinked.  I'm 2/0/7 at the moment with the two being in arcane missiles which is handy for those tricky little rogues and the 7 are 2 in frost warding, 3 in improved frostbolt and 2 in ice shards  and am expecting to spend the last point in improved frost nova

got some ideas of gear, but would really appreciate advice from anyone who has experience of lvl 19 pvp as mage.

i usually defend in the flag room making use of the frost nova sheeping and the frost bolts to slow and CC the horde.

I hve been thinking about doing a mage like this.

looks good to me and i have tried the hunter out with good results.

Specc frost stack stam, the ultimate FC supporter. You kill rogues and get to spam frostbolt rank 1 on people that are after your FC.

Do NOT stack spell damage, you just need a bit, your damage won't keep up with rogues / hunters, so why even try?
