According to the WM activity survey Q2, Horde WPvPers outnumber Alliance WPvPers quite a bit. Q4 says most responders are WPvPers. That’s the only WM faction balance stat I’ve seen. Realmpop, etc. stats not relevant to WM.
If there are simply less Alliance WPvPers, what else is there to do but use Alliance PvEers to supplement? At least with aoo they must kill to complete it.
Looks like we do need something, whether bonus/aoo or something else, to help WM faction balance the region. Necessary to reduce overflow shards, which affects Horde - no enemas!
Fyi: The outnumbered bonus has been at 15% for some time now and no new aoo quest in weeks. How many of each faction you’ll see just depends on shard/lfg. Was plenty Alliance (no aoo) at Stormsong assault, plenty Horde too. Was fun!
