I went erudite, the out of combat power regen is nice (its 24 @ lvl 32 - scaling quite nicely) the AE is the second highest damaging spell we have, after harm touch and on a 3 min timer, oh, and did I mention it was AE??!! also 2% spell crit, a ward that seems a bit weak, hover, and the other stuff everyone else gets anyway. also have an arasai sk (lvl 80) stopped playing him though as it just didn't feel right

Glide is nice, so is wind walker, but both still fluff.
at the end of the day tho, just go with whatever 'feels right' or looks good.
