TANANAC Is the acronym by the way. The Arcane Not-Archer Not-Cleric. Just getting that out there first.
DISCLAIMER: This build is far from optimized, and I have not capped it, however this is by far the most fun I've ever had on a character, and if you're into the journey to 20 rather than just being 20, this build is worth a try. I do not run the math, nor do I spec in equipment because I still consider myself inexperienced at this game.
Also I have warforged, and I have sorcerer. I know if I wanted self-healing and SLAs I could easily just do that. I like halflings. Get over it.

As I said, it is not optimal, but man those SLAs are fun as hell. Would work even better with Arcane Initiate, just another one to add to the combo.
What are we missing?
Spell Penetration, Greater Spell Penetration (Which is why I take it in enhancements), Quicken, Toughness, Insightful Reflexes
Endgame Content won't be as good obviously.
Specialization in more than one "real" element. Force spells are fun, but there's 3 of them. You will be maximizing and empowering two of them for free.
What do we gain?
Absolutely huge healing ability. Playing this build into mid level and I usually did not use all my dragonmarks, and soloing was the same story. You can heal yourself and others incredibly well. There were times I actually just was the group healer and guess what? It worked.
The heals are uninterruptable, are not based on your Concentration, and all but the greater (which is like, heal, anyway) are affected by Maximize/Empower. 10 HP to Full in the equivalent of a quickened heal? Yes please. Having tons of those? Yes please.
Moderate Damage SLAs. I built this originally because I wanted a more exciting healing arcane archer. Hey it worked.
Still able to get SF Enchant and GSF Enchant. So that's good.
Again, this build is not optimized, nor is it supposed to be. It's a "concept" build. Telling me it sucks because it's not the best thing ever or what everyone is doing will do no good. However, coming up with ideas to expand on the concept and make it better is an excellent idea. You should do that instead.
