I like the tether idea a lot actually. With some tweaking, it could be really well used with the game and class. However the super I'm iffy on, for the sole reason that Mass Effect has a move called Biotic Charge. In the campaign it would slow time after. In the co-op multiplayer, it would not, and it would have been difficult to put in. Now that was ok for biotic charge because you could still charge, but the time slowing down aspect is pretty much all this super has to offer. However, the quote at the beginning was pretty badass not gonna lie.
