Fairly relevant thread, as it was the beginning of last month. I’m at work, on my phone, so I’m not going to put in the effort to find a wowhead article regarding the extra +/-10% Alliance players get for turning Warmode on. It was up to 30% at one point, then they dropped it to 20% and now it fluctuates between the base 10% through the above mentioned 20%.
Also, human racials benefit reputation by a 10% bonus, not AP.
