I went from 1500 something all the way down to 1100 something.
Mad, I put in a ticket (something I rarely do) and finally got a response after waiting for over 24 hours. Unfortunately it wasn't a very satisfying response.
All the GM said was that it's a known bug and they're currently working on fixing it. NO ETA.
So, now I have to figure out whether I want to take a break from battling pets in Draenor to wait for the numbers to, hopefully soon, be adjusted, or if I want the chance of continuing to battle and surpass the number required for the monument.
I am NOT a happy camper.
