I've found that if you actually do what the mission calls out for you go up through the rank faster. I haven't played much this week, been busy at work, lol
, but in the prior weeks I was climbing through the ranks very fast because I was doing what the mission called out, not trying to rack up the kills. If you look at my stats you'll see me deads are greater than my kills. If you bomb the hangar and crash to respawn at your base with a new bomb rather then flying back, landind and reporting you do not gain as much. Same way in bomb the carrier. Take this input with a grain of salt, as I am only a player, I'm not a program nor did I help create this game, these are only my observations. I believe that the point system and ranking formulas are fair and just, kudos to the creator(s)!
