for example have stats to see which server has the most active 20-29 WSG bracket, and if im not asking too much already, who those players/guilds are.

this can be done with a regular /who warsong gulch 20-29 which lists only the players for that realm, despite the 1.12 changes.

I have toyed with this idea and other BG related features, but haven't found a solution that I am happy with.

That whole xserver BG thing might also screw it up.

I love that the xrealm lower level pvp actually goes on for more than just 2-3 hours of peak time - the 30-39 and 40-49 brackets especially are beautiful

Xrealm AV's, however, are terrible. It's a retarded race to the other faction's boss, with no real strategy involved. I don't really miss the 6-7 hour AV's, but I do miss the ones that actually felt fun

Now to get back on topic... since we have the xrealm bg's now, most battlegroups have pretty active pvp at all levels. For instance, at 3 am server time battlegroup 5 had 16 WSGs and 8 ABs going at the 40-49 bracket alone. I'd assume the ultra popular 20-29 bracket was at least as busy.
