Seems to have helped dramatically, though our raid this morning was pretty small (~30), I saw zero lag from kills in my mass pulls. My earlier raid with ~50 didn't see much lag either, though no mass kills were really being done.
I think this momentous step forward in lag reduction should be commemorated with a double godly points week! <cough> <cough>
Also, a suggestion: perhaps when minis get placed back into the zone they can reward points slightly higher than trash kills? ~25ish? in addition to their already small chance to drop symbols? The symbol drop rate on them is pretty low. Last I recall, I had to kill roughly 20 to get one 50pt symbol >.< This would encourage people to actually kill them instead of just FD flopping them into nothingness

Everyone usually fades the Duke unless they have 1-2 boxed groups, or a donored DPS out of fear he'll just DT the tank. Arch Bishop *always* ignored unless he's needed for progression because of his mana drain/DT which isn't limited to the temple, it appears to be zone-wide (may be a bug with auras attaching the aggro to people parked at ZI, I've run in to solo him with warrior leaving group at zone in and they get mana tapped and DT'd just the same.) Enji's positionals seem to not be completely functional, unless I'm mistaken (fangs and thorax emote works properly, frontal/behind accordingly, but legs and body do a 360 degree AE).
