Shadestep and TG make normal class movement obsolete, when you consider that warlocks don't get anything beyond natural movement. Especially considering that float only helps them get across long distances, not up them.
There would be no way to balance the system unless they quit picking on those Locks.

So have a route that only warlocks can go over vs a path that titans can go and one hunters have to .... Whatever hunters do that the others cant. Would be a challenge for the map makers then for players to think different and find faster ways. Worked great in titan fall and fps trick jumping goes way back :).
