When a sun breaker uses their super they have extra armor, health regeneration on kill, seven hammers that fly across the map and only has to be in the general area of where your body is to kill you. Oh, and they get 7 of those. Nope, not OP at all.
But, then again a hunter can use shadow shot to shut down their super.
Warlocks with storm trance can just blink around while killing the Titan with lightning. We can also dodge shadow shot normally and wipe an entire team. Add the impossible machines to that and we have landfall as a bonus. Not many supers can avoid shadow shot and kill two sun breakers in one super lol.
