I really want to slap the cameraman in the back of his goddamn head for making the camera violate the poor characters. Seriously he got the worst possible angle...

However, i've just rewatched the video and I noticed why you guys are saying the attack animations are 'flashy'. And- I don't think that any TP move at all will lack that particular light burst because- I mean, pay attention, every single TP ability utilizes has the same light burst, the ARC and LNC both share it for all of their TP moves. It's like a generic 'initiate TP ability' animation.

Which ALSO makes me think that it's a placeholder.
