My only concern about this is when drops get lost in the geometry. THis happened with my guild the last time we did Lab. Luckily, our petition was answered quickly and we were still able to get the drop. Although as most of us know, a speedy response is the exception not the rule.
Since Dev's like people that post a problem and a resolution as well... Would it be possible for named raid mobs to drop loot in a specific place? Like in the middle of the room they are in? Might save some time and frustration for everyone (SOE employees included).
