For those who are curious about this bracket, here are some current facts about the 20-24 xp-off bracket:
1) Perhaps the most active xp-off bracket in wow due to the high volume of F2P-trial players.
2) This bg has extremley fast queue times (instant to 8 minutes)
3) There has recently been a giant influx of horde players due to the horde having faster queue times than alliance, but because of this, the alliance is now enjoying quick queue times as well (1-8 minutes).
4) Unfortunately, Some classes benefit more from being alliance than horde due to having access to better gear (quest rewards) such as Rifle Commander's Eyepatch. This is why there are more Alliance players than horde players in this bracket. Alliance also has access to the best selection of xmog gear.
5) 80 percent of the players in the bracket are level 20. 24 twinks can be found playing on both sides, but there seem to be more 24 ally twinks than horde ones. It is possible to encounter level 24 premades (wth 4-7 level 24s on the team). The alliance seems to field more premade teams than the horde does.
6) BoA heirlooms are BiS for a lot of the gear slots.
