Congratz on the Dagan, that is probably worth more than my last month rewards combined lol
Is actually odd that you only managed 7 wins, I struggle so much with Heirloom in mythic, everytime I see death at the start of the match I know I need to draw very well.
I think I must have had a bad draw. I am busy trying to climb back up and it seems much easier. I still think that they need to change the way you go up/down. Its extremely harsh to need a 66% win rate to go up.
