I must admit, I haven't done the CG or FG run in quite a while, but 33 hours on an Exe axe in a guild instance? Wow. I gotta say that sounds way outside the norm to me too. That musta sucked bro.
The thing I find most intersting though is this one...
Begurgle (5 people in line, 2 who left, and still waited 15 hours
That kinda bears out what the majority are saying, that making things No Drop probably isn't going to help the issue much. Bergurgle's Crown
is No Drop and there's still that kinda line for it?
At this point it looks academic. The vote is nearly 2:1 against making them No Drop, and that's with a pretty good voter turn out.
I'll reiterate my suggestion of removing the PH's and the RNG from the loot tables. The bottlenecks seem to form around the uncommon spawn, uncommon drop guys. Make them a certain pop/certain drop and those lines should go down.
