Warlock... The Sunsinger I play with has an overshield every time his scorch hits an enemy, making him a semi-juggernaut, that along with his high agility stat makes him both fast AND well defended... I like the distance of the glide and the armor (sunbreakers) are super cool as well... But most importantly: the self rez. It comes in handy for level 30 weekly's, nightfalls, and just randomly dying...
