You do not have the PVP population to support such an ambitious ranking system

[Exira]

Queues are already increasing in time and the hype is fading.

You have two options:
Remove data centers and have 3 pvp regions (NA, EU, JP) for JUST pvp and let your pvp thrive somewhat.

Or

Dumb down the ranking system to a viable complexity to match your somewhat seperated and sporadic pvp community.

Personally I prefer the first and know the game launched without data centers so I assume its somewhat possible. It would also fix queue times across all the pvp game types if all of the regions shared their own queues instead of 3-4. The system you currently have in place is reminiscent of League of Legends THE MOST POPULAR GAME. You need to swallow your pride and accept that you don't have the players to fill this as it stands.

Also today I learned that team's in solo queue are matched based on average point totals. AKA higher ranks are balanced with lower ranks on the same team. That gave me a good chuckle ¯\_(ツ)_/¯
