I distinctly remember one time in AH2 I was coming back from a flight up into the Zoneysphere hunting some bombers. As I was RTB, I started descending out over the water and about 15K or so I spotted several formations of bombers and a group of dots low on the water. So, I called it out on country channel... "NOE raid on XX AF coming from (whatever the direction was)." A bunch of folks upped at that field and were starting to engage when I finally got down low enough to come in from behind and sprayed a few bullets into their goons. For the rest of the night all I got was PM after PM about having a shade account, cheating, etc. because their mission got busted. All it was was simply the power of the eyeball and them not ever looking up to notice I was up there. Player experience has to count for something when it comes to predicting where an attack might come or what a giant, moving darbar represents.
What I've observed as far as lack of missions go is that there is often little or no warning. It's rare to see a text that says, "Hey, I'm going to put up a mission in about ten minutes, takeoff about 5 or so min after that." Instead, I see "Mission UP... JOIN!" But there aren't a lot of folks on the ground or ready to land at that moment, so not many join. Instead of trying it again with some notice, the mission poster gets upset over lack of participation and simply stops trying. Well, sorry I didn't just bail after getting my bombers to 20K at long last, but be reasonable. Not everyone is sitting in a tower waiting for a mission. Give people some heads up and I think the chances of a good sized mission will increase.
