Anyone who really has problems with LA-7's on a regular basis qualifies as a n00b. Let me repeat that, if you really hate the LA7 you are a n00b!!!!!!!!!!
I fly the LA-7 alot, I'm pretty good with it, currently 5.6 K/D and over 5.0 skill ratio by innomin8's stats. KBMAN and I will go out and just clean house in LA7's. But the serious sticks here regularly hand me my ass, flying Spits, P38's, F4U's, etc... Encountering any good Spit pilot who has a bit of E or alt advantage spells death for LA-7's. Engaging over 10k spells death for the LA7 against many planes. The only people who have problems are those who let the LA7 dictate the terms of engagement. Probably the same people who whine about HO's. I like to fly right at 8K, and just let people come at me, a couple of evasives and I'm on 'em, and listen to em whine about how impossible it should have been for me to catch them. HELLO, I'm at my best alt, what do you expect? You want to win, engage me to YOUR best alt.
If the LA7 were to be perked, you'd have to perk some other aircraft as well. P51-D, Spit IX, FW-190 D-9, maybe even the Typhoon.
Which I am not entirely oposed to... at least then there would be a bit more variation in what people fly. But honestly, the balance is good right now, not much reason to change it.
One more time, only n00bs fear the LA7.
