Well this may sound repettive but Ill chime in as well.
My opinions are based on the fact I fly 3 times a week, as time allows. Its not like I accumulate a ton of points like players who live on here (SHawk, etc

)
ENY stinks. In my case, its not like I fly anything too dweeby. But when you cant even up a P-51B...that's just foolish.
Arenas...well, it stinks to be unable on any given evening to not be able to link up with your squad.
Perk points....the things that are currently perked should be reviewed. Ta-152? Ar234? F-4C? I'd prefer the perk points stay at a flat rate. Me-262 should be and stay 200 perks. But to wander up to 380 and such....again, just silly.
The efforts to contain the "horde" have largely failed. People just naturally go where the fight is.
Strat really needs to be reviewed. We have airbases where we cant pork fuel, yet ord can be downed and stay down for an hour. Fuels should, and are, a much softer target. Fuels down to 25% restricts the fighter options much more than ENY. Its just moronic to see a lone Typhoon knock down a bases ammo bunkers...bunkers.
Anyways...that's my polite vent.
I enjoy the game, overall...the graphical changes have been nice. But some of the mechanics mentioned above deserve to be reviewed.
