They get put together outside of the mission editor. Micro missions are constantly happening, you just don't see them as they are not made with the mission editor nor are they posted for all to see.
I know most think of me a a "fighter" guy, but I like to join in on missions. Its too bad players feel the need to hide the missions they are running. Do they fear "spies"? Do they fear other tagging along to feed on their work like bustr posted?
Bustr, I dont think it was the 65feet dar change that took out the missions. I think it was human nature. The type of players we have today are very different than those we had years ago. They are the "i want it now" generation and cant be bothered with creating bomber streams with high fighter cover and so on.
When I lead the 444th Air Mafia for years we did missions all the time. We had some that we used often and everyone had their assignments. I would call out a mission name and give a time and we would roll. Other missions I would setup and plan out while everyone was furballin, or just having fun. I'd post the mission and give a time and the squad would load up and off we would go. Those nights I spent most of my time in a buff as a back up so that all I really did was co-ordinate the missions and tweaking them on the fly so to speak.
The Mafia was starting is downward trend as all squads do, I was pretty burned out doing missions Mugz and Taz both took over for awhile but eventually the Mafia closed shop. I join OddCaf and the 47 Ronin and he planed many missions for the squad. Again we had good participation and the missions while pretty wild were always fun. But the game continued to change. It became more important to land big numbers of kills so some of the help wasn't really much help, and the defenders didnt want to fights us, they just wanted to pick us to rack up kills. Kind of took the fun out of the game, many of that squad quit with in a week of each other.
And so here we are now, low numbers, nobody running or joining missions, players running from fights as soon as they blow their first pass, players hiding in ack, players waiting to resupply town/fields before the attack even does any damage. Things need to change to bring back the heart and soul of this game. Gamers are use to rules and having to do certain things in a certain order to accomplish what ever their end game is. Add some rules, make more important or less important to GUIDE the players into bringing bad the interaction of players VS players again.
