I don't know if we've discussed this before. I'm sorry if we have. 
All pictures we've seen of the Channeler so far is that of some boyish-looking man-child of a human, so I got thinking - Is that all we can play? Ultimately, I'm sure we'll have quite some opportunities to customize our channelers wheter it's in gear, faces, magics or skills. I'm sure of it. But that's not really what I wanted to talk about.
I wanted to talk about races. Not entire races as such, but wheter or not we'll be able to racially customize our channellers. To use an example, I'm sure that a lot of us have played Dominions 3. For those of you that haven't, in Dominions 3 you are a God. Or more specificly, a Pretender to become the next Pankrator (All-Ruler). Anyway, when you start a game, you get to customize your Pretender - first and foremost by choosing what kind of Pretender you want. There's the "Fiery Floating Head" pretender. There's the "Half-Man/Half-Spider" pretender. There's the Dragon pretender. There's a number of undead pretenders. There's human pretenders. There's even pretenders that can't move, like the Giant Stone Head or Fountain of Blood.
Will we have, or should we have, a similar opportunity in Elemental? And if so, what kinds would you like to see?
Personally, I'd like to see an array of human-like Channelers, since we're not actually going to be actual gods (but I'm sure as hell going to act like one). Dragons are already pretty much out of the question. But the Half-Man/Half-Spider, perhaps? Or the Liches. Or a Avariel-like channeler. All able to potentially radically change what kind of channeler you'll be, or what advances you'll have access to as you level.
I'd like my Channeler to be the great Bear-father, able to "shapechange" between a big bearlike but regal man and that of a spirit bear. For no other reason than posing as the god of bears. A druid-that-is-actually-a-civilized-mage. Hell yeah.
Addenum: I don't care how silly that last part sounds. I've always liked the idea of beefy-looking magic wielders contrary to that of the aged man in his study with a mass of books and an oversized head. So ha!
