Remove WSG CTA so we can play more AB and AV

[nesh1905]

The only battleground we get to play during the week outside of Call To Arms is Warsong Gulch
Only getting to play Arathi Basin or Alterac Valley for 1 weekend every 3 weeks is bad for PvP content
Warsong is, in my opinion, the least suited battleground for large scale pvp, when both teams are full
On both AV weekend and AB weekend the PvP activity is MUCH higher (a lot more players queueing BG's)
I would LOVE to see a poll about this on discord
