Why concern yourself with what idiots say on channel 1?
If some guy starts whining about being bounced by any aircraft being piloted to its strengths, he needs to get off the deck, develop some SA and learn how to counter slashing attacks.
It's very common for noobs to whine because they have no clue how to deal with fast fighters... In others words, have enough alt and/or E to avoid being an easy target. Turn into your attacker, work at breaking down their energy and cause them to fight your fight. The problem for noobs is that they have no clue how to do that. In fact, a fair amount of experienced players have no clue about this either, which is why so many whine about the La-7.
Don't worry about what people say, don't worry about La-7s, Spitfires and the like. Spend your time thinking about how to kill them.
General Grant said it well when he told subordinates not waste time thinking about what the enemy is going to try to do to you, but be thinking about what you are going to do to them.
