Let me begin by saying I'm not pushing this idea, nor am I thinking it would be a good idea or bad idea..... its just something that came to mind.
The populations in the mid-war and early-war arena's are anemic at best. What is everybody's thoughts on changing the format a bit. Each month, we restart a Tour of Duty. What if, in order to encourage a varied use of planes the course of a month was planned similar to the course of a war?
We have four weeks in a month...
Week 1: Early War plane set
Week 2: Mid-War plane set
Weeks 3 and 4: Late War plane set
Wash, rinse, repeat.
Additionally, each arena could have a single persistent map throughout that month (War-winning resets not included, but they're somewhat rare anymore). Also, you'll note I only included 3 arenas.... because lets face it, there's never enough people to warrant 4 arenas.
Arena 1: Larger map, follows above planeset rules
Arena 2: Smaller map, follows above planeset rules
Arena 3: Smaller map, does early-war plane set week 1 and 2, mid-war on weeks 3 and 4
(alternatively, the larger map could do mid-war 2 weeks and late-war 2 weeks)
Anyway, that's just a solution I came up with to the hanger queens, and also to encourage a more varied experience. Unless somebody is really that anal about flying their late-war planes, something tells me they'd still log in and fly during the first two weeks of the month. And if they want to rank highly for that month, then they'll fly early and mid-war.
Flame away at my idea, but keep in mind, it's only meant as a thought experiment. I'm not even sure if its possible with the way they have arena's set up. I just know if I went to all the trouble to develop a game with this varied a plane-set, I would enjoy seeing it get some use, as well as this might encourage HTC to add some of the early/mid war planes that people always ask for on here since they'll get used at least part of a month.
