i will not say that the raiding community is dead, but let's say it's not as big as before... and will not go better i guess.

the reason vary:
- new player have a hard time to join a static, a lot of static are quite elitist (not all ^^)
- player have a life and will have trouble to schedule content like this.
- some player will simply not find it fun to repeat over and over and over content for do bunny jumping
- the lack of replayability of the content, loot =/= replayability ^^

and i'm sure other people can give more and more reason of why this situation is like this.
