Just a bit of commentary / observation, ignore if you're looking for something deeper.
So, I leveled mostly as fire, giving frost a little burst mid 60's but hit fire again for heroic viability (no raids for me - I find them stressful).
Now with the leveling bandwagon back in town, I decided to give frost a good run as a bona-fide leveling spec, and I must say, I'm loving it .... I have in the region of 800 spell damage, so it's not amazing by raider's standards, but I'm telling you - it's plenty good for questing.
What prompted me to write this, was something that happened last night ... I was doing the march of giants quest in HF ... which required the downing of a level 70 elite rock giant. So I kill a mob, and FoF procs on my kill shot, I then notice I had Brain freeze up as well.
Some quick thought about how best to utilise the situation, and I pulled out my water ele ... the giant was close by, so I nova'd him with the WE's nova. Then opened with Fire blast ... which crit, but didn't break the nova (FN glyph ftw), then the insta fireball, which also crit (don't you love shatter), and broke the nova.
Then an Icy veins frostbolt/icelance combo to make use of FoF, and almost instantly (ok, about 2-3 seconds in), I had him half health ... I felt godly ... so with me and the WE firing away at will (FoF proc'd again) ... I dropped my first same level elite before he could take any HP off me at all - he got to me, but FN and another shatter combo sorted him out ... DPS for the fight - 2k ... 30k in about 15 secs. I felt more powerful on my mage than I ever have before .. it was intoxicating ... I suddenly felt the whole world opening up to me ... and it was cool.
Just to highlight a difference in style here ... I tried arcane ... with it's promise mobility and insane damage... and I hated it ... I finished every fight at half health and mana. I'm sure I was doing something wrong, but I hated it. Others have raved about Arcane to the extent that they're sure that a nerf is incoming very soon - I don't see it, but hey - that's me.
So, to sum up - Frost, for me, is most definitely the best leveling spec ...
