You know what would be really strong in a capture the point game mode that is dominion? If a class could put up wall around the capture point that maybe gives a regenerative over-shield like a warlock rift with some sub-classes. I think it would be a bit over powered though if you could see through this wall or if in some drug induced fugue state this wall also dealt an insane amount of damage to enemy if they touched it. Thats a wish list though and would obviously be overpowered in such a game mode but thats my feedback for a new class ability.
