Many ppl want to go to alliance but they just wait for free transfer like it was before. Consider that most of players have few chars and they wont pay to transfer all.
We had almost balanced server when horde-ally free and ally-horde closed.
Now pvp isnt fun anymore and in many cases not playable at all, but yet only little % of players speak about it on forum.
Ppl still leaving server. Off course now we have new season so theres growth of population but after ppl get s4 we gona have huge decrease of pop.
I guess warmane want to earn as many as possible on this realm. They dont care about realm wchich left few months before it get empty and wipe.
