Greetings,
I know you're busy with the rankings atm, but I have noticed a few things about the missions I felt needed to be mentioned.
"Zombie town" mission is not worth keeping in the server, IMHO. Myself and another player spent 45 minutes running around the whole mission looking for the zombies to kill. Apparently one (or none) remained and never cleared for the whole 4hrs denying a different mission for popping. I would like to suggest the zombie town mission be removed from the AI mission list.
Something a few of us have been discussing (not sure if you can tweak this), but the missions tend to spawn near eachother (ie all up in the northeast, all in the southeast, northwest, etc). It is very rare for a mission to pop in the northeast, one in the central west and another in the southeast or spread out.
Spreading them out will challenge players to make a decision which mission they will attempt to engage, closest to them or the one farther away that someone else might cap before they get there. I haven't looked at the new AI mission code, so I don't know if it can even be done, but I would like to suggest spreading out the missions if possible.
Thanks for reading
