@hayhor actually what is missing is CTF or conquest. It is a basic staple of all PvP where two teams of 30 players either capture flags or conquest the all bases on the map. This would work either way - as we have seen in the limited event they called Control. I wonder if it will ever return as a permanent feature?
I think the "real issue" is head count. If the population trots off to play conquest and no one is queued for the BR and AR, they will be harder to fill with warm bodies. In the end, I suspect they will not make any major changes unless the population grows, but that is the catch 22. The population will not grow when the game stagnates in the swamp of mediocrity.
