The major problem I have with them is that PvP requires continous updates. If we look to 6.1 we got a major content dump, and they had a lot of potential "light switch" fixes open to them. They chose not to flip the majority of switches until months, sometimes even years later in the expansion.

7.1 will need to show, not tell. They either implement major changes that rejuvinates PvP, and keep up with minor QoL fixes, (And not just for 5v5 modes), or they let it fester for another 2 years until 8.1. PvP has a lot of potential, I hate to see how much of it they throw away.
