At the moment 19 queues are not happening. However as a community we will have to organise queue times and make it happen. I found when queues were popping they were faster on alliance although im sure either side could use a monk
The 19 bracket may not rely on 10s but having them queue certainly helps get pops as opposed to none. From what i can see though many 19s are moving to play 29s.
Medivh is the "home?" For level 10 twinks. I am not going to apend much more RL money on wow. Havent bought WOD either. Basically moved all my chars in cata
On my 10 druid in guardian spec with violet hat (2 rating) i get 40% reduction and 2AP. In skirmish it was scaled bsck by half (20%). Feral grants none. Hope this helps.
