In my opinion is it really necessary to have a avatar for the human form since DC is MORE than fighting in dragon form only!!
In the Raven you must conversate with many NPC's and it would be stupid to NOT see you own character all the time walking & talking in the Raven and going to your sexy skeleton princess (with two big round bougies like apples so nice) to give her a kiss etc etc ...
DC has, besides RTS and TBS parts, also a RPG part and I believe this RPG part include & need a human avatar !
And to look at your human character shapeshifting into a dragon on a platform in a (kind of a) garden at the Raven will be fantastic cool !!
What do you think ?
