Hunter blink is OP and already broken before it even starts. Shotgun blinking is back and they can dodge/shift/teleport every 9 seconds.
Titan overshield on demand is OP and already broken before it starts. Overshield shotgun rushing it back but worse. Imagine 3 Titans doing that to a control point or heavy.
Warlocks will not be seen in PVP because they get a weak ass PVE melee and have the slowest melee in the game to start with. This will seal the fate of Warlocks as a strictly PVE class.
