Well they do. Why do titans and hunters get to excell whilst moving yet Warlocks cannot? Roaming supers aside, Warlocks are healers or support primarily, yet those things require you to be stationary, the well and rift being what I'm talking about. Healing is a Warlocks forte, so it should be something they're the best at. I don't think having the rift follow you where you go is too op. Its needed actually.
