No idea. This is how I lvled my heroic teams all the way to 115. Now that all my guys are 115, I am just noticing the other day that the exp and aa bar never move after hours of grind even though they were getting raid xp msg.
There’s penalty and there’s not working at all. Got my Groups from heroic to 115 in less than a week using raid killing. Now, the AA xp bar isn’t moving at all. We’re talking three decimal accuracy. The number was not changing at all after days of killing.
