Here is my assement.
The changes were done without testing or thinking thrugh some key issues, like ENY, squad communications, arena caps
The arena caps being used to "force" players to try the new arenas after their first choice was full. This is probably the most maddening to me.
I would have not one problem with the new arenas, had the original MA just been left as it was. I don't see any reason that this could not have been the case, since Pyro has stated that the issues driving the change had nothing to do with the server, connection or anu technical issue.
The MA should have been left and the others added. The palyer base is smart enough to fly were they want, withought being coerced into a decision.
Also, the small maps seem like a step backward.
After being a customer for 5 years, I think this change was implemented in a terrible, thoughtless way.
I closed my account for now.
