There is a bug in Alterac Valley on the alliance side of the map. When an alliance players dies at Snowfall Graveyard, they respawn all the way back at the Aid Station graveyard in the back of their main base. This respawn puts them at the farthest point away from where they actually died. They should be respawning at their nearest accessible graveyard which in this case would be Stonehearth graveyard (if not capped by horde).
Thank You for looking into this.
