I'll keep this brief so i don't delve too far to the d000m!!! side . . .
There are two raids that are routinely run at this time, FOT and CiTW. All the other stuff is barely run, even Shrouds take 30-45 minutes to fill.
The old raid loot just isn't worth pursuing, and the pursuit of loot is what makes people run things more than once.
Quite frankly raiding is dead in DDO. The the new "expansion" coming out without a raid makes this look like it's not going to change anytime soon.
My question to the powers that be is . . . are you aware how screwed up the current situation is, do you care, and is anything going to be done to re-sexify the old content so it's worth running again?
Raiding is fun, the current situation leaves a big hole in the end-game.
