Hi guys. I'm extremely new to the community, but perhaps my unbiased point of view might help...
It seems like the way it was, most of the people were forced to take late-war aircraft, which made the early war planes extremely rare and difficult to master. The newer arenas make sense, from a "game design" perspective. Why create a flight sim than spans the entire WWII history if you're not going to give the early rides a place to be free of the late war advanced fighers?
Who wants to fly around in a Spad when your enemy is flying a F22 Raptor?
The problem is, it looks like the community size of AH wasn't large enough to support this change, which is unfortunate. It basically cut your arena sizes by 2/3, which apparently means a lot less fun for everyone. The solution, of course, is to get new players into the game.
I have to say that I probably would not have signed up for AH under the old arena system. I like flying ALL of the planes in a sim. The old arena would FORCE new players to fly only late-war crates. That, to me, is silly.
