This move is too op to not be available on all subclasses. I can promise you that Bungie is well aware they made a huge mistake in putting this move into the game. You can't have a few people able to avoid death where many else die. You can't have a few people able to gain ground so fast and not expect it to be fair to the others.
Since day 1, blink is the #1 reason voidwalkers and bladedancers rule pvp. It's still a huge problem.
EDIT: Hehe... I love when I get everyone's panties in a bunch.
