Hi guys, need little help about speccs for lvling atm 72 lvl mage.
If you guys can help me to make 1 good frost and 1 good fire specc for lvling.

imo, if you are lvling in the 70s spec arcane, get slow and barrage and faceroll to 80 with ease.

Most elite quest mobs are snarable and easily taken down as arcane solo (the 5 man quest "...,Scourage of the North" comes to mind).

Drop points from wherever to get Precision if you tend to work on orange/red quests. Leave them out if you focus on green/yellow more.

From there fill out arcane and you're set.

I loathe fire. Frost has always been my playstyle. Someone else will have to help you out there.
