Here is the problem Draenei, with Shamanistic focus and rage by level 40 shaman has no down time as a enhancement shaman.
Also as far as gear leveling it is much easier to find melee dps gear, lower level caster gear lacks raw damage and generaly so you really never have enough to scale as well as rogues, warriors, and other melee classes.
Not saying leveling as an ele shaman is bad, just harder then leveling as a enhancement shaman.
I personally leveled enhancement, this was back when ele had no viability until level 60 for pvp.
If you want to level your shaman a certain way, this goes for anyone wandering, do it.
Your toon so have fun, I will say yes enhancement makes leveling pretty easy, but if you made a shaman to be a Caster, or healer, go for it if thats what you wanted. but I also want you to know, enhancement is considered our leveling spec because it is, but doesnt say you have to.
just like pallies have ret, warriors have arms, demo for locks, beast mastery huntards, shadow priest, etc etc...
btw Mistress Draeneipally you forum alot huh, 900 posts and I swear to god you just started lol.
As long as your having fun
