In my observation, there are lots of current high rankers who started as lower rank, lower skilled players and ranked up through unstrategic dropping, camping, and general kill mongering. And yeah, you can tell who they are, because (a) they prey only on noobier players who can't keep up even if they drop their own bomb, (b) they are not too awfully hard to kill head-on and in a first-turn double-tap with my bomb still strapped on, (c) they are pretty easy targets once I drop my own bomb, which I will do because of [d], and (d) they leave when they are outmatched in a bombless turning fight, to go find an easier game with noobiers. Oh and (e) they can't cover a bomber to save their own life; in fact, that's all they do is save their own butts, and hardly actually cover anyone. (Covering would require killing an enemy who is the "right now" threat to a bomber, not just killing an enemy and saying "well he coulda killed ya at some point duh.")
There is also a second group. These are some current high ranked players who play strategically to win the game, use bomb dropping with strategic timing, actually support bombers with timing and flanking (instead of just mopping up kills as their own teammates are dying... big difference there), actually do shoot enemies from the side, above, and below, by skillful leading of the target, avoid teamkilling whoopsies (what good is covering me if you keep hitting me and saying sorry), and return to base instead of camping, to pick up a bomb that they might be able to deliver since they are not the exclusive "cover." They know the difference between random acts of dogfighting that only looks like you're covering, versus well-timed covering where you help a bomber from getting killed real-time. These players also know to distract and tie up enemies far afield, instead of just sending a gang of planes back to spawnpoint just as I'm coming over the last hill. They know how to cover bombers because they are bombers themselves at least some of the time. They cover really well, with a bomb and without a bomb. They get thank you's from me when they give great cover, and they know when they did not have a good run and didn't make enough of a difference - that's when they say "sorry man, I was trying to cover you but I didn't get 'em."
This second group is frustrated because they get accused of being from the mongering first group. In fact, most players from the first group falsibly justify themselves as being from the exalted second group. The confusion is understandable, since they kinda look alike.
Plus, members of this second group are a rare find, as there are only three of them.
