Don't hate on people for putting time and effort into something then being good at it... also 50 kills and the deaths u stated doesn't sound like they are good at all.. the so called OCD brigade wouldn't die in jets unless it was a ram crashing etc.
Plus a little tip for you... don't play on fast respawn servers!
I don't side with him on the 'no lifing' aspect of air. However, air is way too powerful and it is never particularly fun when you want to just stomp around between points on foot but you happen to be on the team with either no good pilots or no good pilots willing to fly that round and that is the deciding factor on who will win... then you add to that when you leave that game you're now in an arena where your stats are being directly compared to the stats of people who are essentially not even playing the same game as you and are in no way balanced in terms of score and k/d.
Whether you like flying or not, it's just a horribly balanced aspect of the game in every way imaginable.
