Pretty straightforward here, if you’re a horde, choose horde, if not the otherwise.
Set up your Battleground
PLEASE MAKE SURE DO NOT MARK THE OPTION “ USE RANDOM BATTLEGROUND” IF YOUR TOON IS BELOW LV80, OR IT WILL CAUSE SOME PROBLEMS.
Choose the battle place you want to give priority to, 1 for your first choice, 2 for your second choice and it goes on.
So, your toon will choose the battleground according to the priority you set in the above settings, but it will also queue up for the other 3 battleground that you have choosen. For example, in the setting above Warsong is your second choice, but you may get into the BG first, so your toon went in, fought around a little, THEN, our first priority BG: Strand of the A is queued up, then your bot will automatically switched from Warsong and straight into Strand. The conclusion is the bot will only switched battleground from lower priority to the higher priority battleground and never the other way round.
