You have a helmet that gives you healing and all your abilities back when you use a super, a helmet that gives you extra armor and life steal on hit, gloves that give you 2 of your melee abilities, and gloves that give you quickdraw and speed reload with any gun. You're not exactly starving for exotics in any way. As for mobility you just have to learn to warlock surf or warlock skate whatever you wanna call it.
