In arena you can switch talents before the match starts, then when the match is over and you are back into the live world your talents are as they were before.
But in BG when you switch talents your switch stays with you after you leave the BG.
Why is is this? Surely both should work the same way to encourage you to swap builds depending on what your BG will need.
As it stands right now i have to play feral affinty and master shapeshifter in BGs otherwise when i zone out i can’t do any damage while questing until returning to a rest area!
