I've been following this for several days. Don't have an oar to dip when it comes to end-game raiding, but I would like to point out to those who are concerned that their "fair share" of slots aren't being filled by <class-of-choice> ...

Playing Bard is fun as all get out. Playing Machinist is a chore at this point, it isn't as fun. Perhaps the popularity in raids is more of this (fun vs not as fun) and less of that (I can do 500 more damage).
