Blink strike only one shots from the back, how is that broken? (If you mean arc blade then ofc, it's a -blam!-ing super it should one-shot not two shot) Arc bolt barely even gets an enemies shields down, firebolt literally does more damage then it, and pretty much any jump can do what you described, btw it's also on warlocks lol, but you don't point out what warlocks have, do you? How about starting with void walker since we're on that topic, let's see there's blink, then there's the seeking grenade (I forget what's it's called) which can do the same damage as the arc bolt, but from a greater distance, or one shot an enemy with the exotic, then there's scatter grenades which can be thrown from huge distances and either do the same damage as arc bolt, or one shot with exotic, then there's the super which grants extra health when casting and can clear an entire team if used correctly, and then there's the range melee which can give you over shield. You see how every class has there own op'd qualities yet? Or you stuck to be biased? Sunbreaker is just as op in some ways, the melee is more powerful then hunters, the super is more powerful then hunters, the grenades are pretty much the same as the hunters, there's a lot going for it not just one thing.
