I'm glad Frostwolf has no 40 man bgs
I do bgs on both Icecrown and Frostwolf, and the 40 man bgs are one of the many reasons I prefer Frostwolf. Sure, it sounds great in theory to have all working content, but 40 man bgs simply weren't designed with a smaller private server player base in mind.
On Icecrown, it seems like the 40 man bgs (at least when I used to play them a lot- I stopped) suck up a disproportionate share of the queue pops. And inevitably, one faction will be much stronger in some bgs, which means a lot of the losing team will leave early to do something else, and that will suck up even more players to go join a losing bg.
Plus, the individual or even a premade has a hard time making a difference in a 40 man bg. It seems like a lot of undergeared players queue the 40 man bgs specifically because they just like hanging out in some big zerg where they can hide behind their geared teammates.
I think if they ever do release 40 man bgs on Frostwolf, the problems will be much worse than on Icecrown, due to the much smaller player base. I personally hope they don't and that, if they do, they strictly limit how often they pop.
