The real elephant is calling hunters FOTM. Theyve always been popular and dominated bg, even with ammo pouches and mana.
I personally run into a lot of alliance premades as horde, but being on the horde f2p community has given me a lot of insight into how its probably done on alliance: everyone is making random bg groups all day long, especially during peak hours, and freely advertising for more or that theyre lfg.
Us just single queueing is always going to feel unfair like this, but even so, I get matched with decently geared enough ad hoc teams regularly, even against these premades.
Seems I'm always queueing while bleeding hollow is wrecking us though. You guys are just ruthless. If I get a kill on one they hunt me down and keep me dead longer than I'm alive.
