The devs explained it

"This is a big change to Battlegrounds matchmaking which we are executing partially in response to player feedback and partially as an experiment. We recognize the change will prevent players from being able to reliably team up with friends in Battlegrounds, but it should also improve both the speed of matchmaking and the competitiveness of PvP matches. As part of the change, we are resetting the matchmaking rating (MMR) of all players, so going forward, the system more properly evaluates individuals based on their performance in the solo queue. We’ll be closely monitoring both player feedback and the impact of these changes on the system."

I felt the same way when Battlegrounds was released without a CP option.

If you want group PvP you can go to cyro at any given time. That BGs finally are solo only is brilliant. No Premade groups anymore that steamroll 2 random Groups. That destroys the fun for 2/3 of the players. As long as ZOS has no system that only let groups fight against groups it is better that way.

It's an MMO, they should give 2 options for queues. Let people play as they want - with friends or solo

and with CP!

It's not permanent. It's an experiment to test mmr and matchmaking with real players. That's exactly the point of the pts- to publicly test things.

We should be clear that "experiment" is not the same as "temporary." I read what you posted as "We are testing this to see if we want to keep it permanent". In addition, given the uproar, if it was only about the test servers we would have had that confirmed. This is a note about what will happen on the live servers if they decide to go through with it. Might it change in a future patch? Sure, but for now, that is what live servers would experience.

The more threads on this the better, but I also suggest everyone with an opinion on this visit the PTS forums and weigh in (full disclosure: I started a thread on this because I care quite a bit about making ZOS know how much some of us dislike this change).

@svartorn If you think Cyrodiil is broken and unplayable, you propably play only on Zergling Campaigns like Vivec or Sotha Sil, whatever they are called now. I have no issues in Cyrodiil besides those that are related to broken Tankbuilds thanks to CP.
It always runs smooth with a Ping of 60-90 at stable 50 FPS.

And no, ZOS won't remove groups out of Cyro, it is technically an AvA area, it is intended to let groups fight each other.

Edit for bait.
