Greetings, all!

I'm currently a first life Human Sorcerer16 (True Neutral) with the ability to jump to 18 pretty soon. (Waiting to finish Gianthold quests.) I'm enjoying blasting so far (because enemies, even if charmed, have a hard time killing themselves). I wish to plan ahead.

Once I'm done in Gianthold (and level 18), where do you advise I go for the best gear/XP for my level? I can farm a bit, but I'm presently in no mood to spend weeks or months farming Greensteel and ingredients. I'd like to explore the content I'm paying VIP status for.

For levels 21-28 (but especially for 21ish), what school should I emphasize as a Sorcerer? I like blasting (and am primarily an Air Savant with a minor as a Fire Savant for wall of fire); I chose Air Savant because of general utility (go, go Feather Fall!) and because few things resist electricity that much. However, I've heard Enchantment is the school to max the DC for in Epic. I want to be as useful as possible, preferably able to solo Epic Elites. (Soloing Epic Hards or Epic Normals is another goal.)

Also, what Epic Destiny should I pick? Magister and Dragon Incarnate each look spiffy. I'm not sure how Twists of Fate work, nor if I should try to mix Magister and Draconic Incarnate.

I probably also need lots of Epic gear to make my DCs high enough for things to be worthwhile for Epic Elite instances, and perhaps also for Epic Normal/Epic Hard. I've not spent my time farming gear; I have no Greensteel items to my name, and have mostly gotten by via random loot drops. (I figure Epic gear will be easier to get than trying to farm Necropolis or Shroud for spiffy items. If I'm farming, I may as well get the best stuff.)
