When a Race occupies the Battleground, it may benefit from the Faction Bonus a second time per Race (i.e. conquering 2 Regions - or more - of the same opposing Faction Race in the same turn will grant it 2 bonus VC).
A neutral Race occupying the Battleground can choose to fight alongside the Alliance or the Horde for the duration of its turn and temporarily benefit from the Faction Bonus as well as the Battleground bonus described above. At the end of its turn, this Race is considered neutral again. On their next turn, if the Battleground is still under their control, the owner of this neutral Race may choose again between the two Factions, regardless of their previous choice.
