Me and several other guys, who where not even twinks or in that twink guild but were more active than any twink just got bored and leveled. Sitting here whole Saturday afternoon for three 6 vs 4 games is not worth the time.
For us it looked like ally levelers were so used to free ride at 19 on the back of 4-6 men full twinked rank 3 teams, that they just refused to queue up if the game took any effort after single defeat.
Maybe you queued at wrong time? Almost Thirty usually plays at 9-12pm server time.
We have core members now reached 29 and twinked but horde doesnt deliver any challenge sadly. Anyone who wants to twink should go horde now.
