It wasn't particularly difficult to kill any of the trash so long as nobody over-pulled trash (2-4 mobs at a time, ideally). More people makes the killing more efficient, but also keep in mind that more people in the group, means more people rolling on the rep tokens unless you can get them to agree to pass on them for you.
