I hate to say it, because it’s the last bastion of Alliance vs. Horde. There’s some meme energy and charm to keeping the game purist 10/15/40 Alliance vs. 10/15/40 Horde. But every expansion we go through the same song and dance; one faction is the PVP faction and dominates. Both sides feel slighted and it turns people off from PVP before they even invest time, which is not good for the health/growth of this side of WoW.
In the pursuit of fair matches and quicker queue times for all, I’d vote for the teams to be homogenized and the matchmaker either be fully randomized or attempt partial fairness by sorting the ilvl and roles between the two sides.
