Simply put, we don't have them. Out of all of the exotics that warlocks have, a whopping 3 of them are worth putting on in crucible. Transversive Steps, Ophidian Aspect, and Sanguine Alchemy. Contraverse Hold used to be up there too, but now that's made null by the fact that it only works on the [i]worst[/i] subclass Warlocks have. And the few exotics we do have do almost nothing really gamechanging. Steps and Aspect are both passive buffs that do nothing but save a little time, and Sanguine Alchemy is useless until you have a rift up and you find yourself in the [i]very[/i] situational position to use it. Every other exotic we have is almost exclusively tied to ability regen, and that doesn't really make too much of a difference when our grenades have no utility outside of chip damage, our melees all make little difference whether they're charged or uncharged, and our rifts are more often than not a waste of time to use. Why can't Eye of Another World [i]actually[/i] track enemies instead of highlight them in red (which is really only useful if you're blind.) Hunters have Foetracer, which at least has uses, and I don't even need to mention Titans. I could give a laundry list of exotics that Hunters could feasibly uses in Crucible, and for Titans I'm hard pressed to find an exotic that CAN'T be used. I don't want OEM for Warlocks. I just want an exotic that does something I can play around, not some passive regen buff or increased weapon handling.
