Honestly clearing time depends entirely on your group. I just made a run of Taral V without wipes in about 30 minutes with a good group (including the bonus boss). It really will shorten down once the mechanics get polished and people actually "get the hang of it" at least that's what I think. The only thing that is really annoying me is the "return to medbay" thing. Really if I'm going to spawn at a further point of the fp anyway please don't make me sit through two loading screens just to get to that starting position, just spawn me at that "checkpoint".
