Would be interesting to 5box a raid...would be a bad thing in kara though due to the group diversity usually necessary and limited slots, but like Mote said in 25mans that's just as much a boon as a bad thing; 5 of the 25 actually doing what they're supposed to and fairly focused dps rather than a few guys screwin around or not focusing right lol; however if you fuck up, you lose 4 or 5 people at once(eg getting hit by a void reaver arcane orb) which is the downside.
