We had a dps get punted off the side every time... just like in the trailer ><.
What I really appreciate about these early flashpoints is they have REAL mechanics. You CAN wipe to standing in bad things. My group finally got it down the first time I ran it because I (the healer) dinged in the middle of the fight because of XP from the adds and tehrefore went to a full force bar to heal through the avoidable dmg everybody was taking. It's pretty intense.
Also: that bridge over the asteroid chute they show? OMG it's worse than the elevator boss. We didn't know what it did the first time & everybody got turned into space dust.
