I agree completely with WWhiskey. Lots of people like the dynamic of MW, not everyone wants to be a fighter jock, and it allows players to do it all; gv ,cv, bombing etc. without suffering the idiocy of LW vulch fests, uber everything aircraft, jets, rocket and the same map for a month syndrome.
The hoard rarely stays in the majority very long, and great fights happen all the time as the dynamic shifts. Lately MW seems to be a venue of LW peeps to fly around and farm perks in low value rides for B-29s. So what, makes for some fun buff hunting if you want to chase a few sectors.
People change sides all the time looking for a fight. The 1 hr limit is a smart way HTC, to keep people from abusing sides for strategic purposes, don't hold your breath they are going to change it to please you. Way too many other opportunities to dogfight elsewhere.
Axis v Allies, which is a great venue for ACM and good fights, which is usually base capture restricted, it is also sparsely populated but lots of fun when it heats up. The quick side change works fine when there is no strategic advantage to be gained.
Stay in LW, WWI, go to the DA or AvA if it disturbs you so much. Not a small number of regulars like it the way it is regardless of the numerical odds for and against you. Enjoy
