Anyone can find it easy to survive in this game flying at 30k.
A: hardly anyone is up there.
Two: Even if they are, it's really hard to get a kill. If you practice enough you can, but so few times is the skill required, it's hard to get practice.
Sir, I am an unapologetic alt monkey, I fly at 30k a lot. I would put forth the contention that if you yourself do not fly at 30k then your statement of "hardly anyone is up there", may simply be that you do not know. Unless you are up there you probably are not observing whom is up there with you. Time and time again I find many guys flying around between 20 and 30k that think they are safe, they never look up. I know this because as I approach them they are making turns slowly left and right, as I do when I am looking for targets below me. Many of these players never see me coming. I am up there because I like the hunt. I don't care what it is that comes into the area I am hunting. I expect bombers but I find many fighters. Maybe they are hunting bombers also, I would not know that. Flying at alt is a different skill set. Aircraft performance is obviously greatly affected. The match up between different aircraft types is greatly affected because some planes do so much better at alt than others.
I have said before, "I dont mind fighting on the deck, I have fun there too, I'm just not going to start there.
They "Zoneysphere" begins at 30k and goes up from there. The air is cleaner, there is no pollution and the unfiltered photons go directly in to me making me much more handsome.
