Currently trying 18 arc/33 fire, it's doing great so far.Of course i do miss presence of mind sometimes but combustion is very useful too, it can do very nice damage with blastwave plus ignite 5.So far i have tried:
16 arc/35 frost.
21 arc/ 30 fire.
28 arc/23 fire.
31 arc/20 fire.
18 arc/33 fire.(current testing spec.)
I find fire the best for pvp if you have good crit items that is, i have loads on my mage and it makes a nice difference especially with incinerate 2 and critical mass 3.However frost slightly edges it in pve i think due to the iceblock and ice barrier, though now i got high crit rate i would say on instance bosses scorch really is good now.
