Don't like the idea of a rps.
Some poeple actually like to fly disadvantaged planes.
All I really fly are the ponies, though. I will go on the deck, slow down and fight anyone. I don't care if I die, but I like to take on the turning planes and planes that I'm not *supposed* to be able to dogfight. I die all the time doing this.
If people like to fly the slow planes, then that's really a choice they make. Don't penalize other people with a limited planset just because you like to fly early war birds.
Maybe have a rps arena for those who like to keep things more on par. I'd bet that not a whole lot of people would be in that arena though, compaired to the main as it is.
For me, I like to just up in a pony and get to the fight quick, have fun for a couple hours, then log off. I don't care what anyone else flys.
