I've had the pleasure of being apart of a few 12 man cities recently and they were a lot of fun. I was wondering if this could be considered in the future and it wouldn't need a lot of changes as the instances already pop on accident from here to there, simply code it to look to create 12 man instances. Cities already have a lot of issues but I believe this could help out the whole city (shitty) stigma and breath a lil bit of life back into the game.

Thoughts?
