I am extremely familiar with the finer points of combat in elite. I started playing in beta and have put many many hours in since, primarily doing combat activities. I have flown many ships over the years with many different styles, against both players and NPCs. In addition to just playing the game, I've spent countless hours by myself and working with others to test and figure out the finer points of how various mechanics work, and really get the game down to a science. The thing that kept me so engaged in the game was largely the flight model. I love the interesting mix between space combat and old-school dogfighting. That star-wars-ish cinematic flying is what sets the FEEL of elite apart from other options. That FEEL of the game is what keeps getting eroded, and since that what kept me so deeply interested in the game for so long, that feel going away means I go away.Go ask a combat flight sim about turning circles and their importance in a dogfight. If I can turn inside your boost turn radius I cannot lose the turning circle fight. And it's very likely that I will win it and make a bead on you. Something that makes going for gimballed weapons nothing like a "scrub" choice: there's tactical use for firing off-boresight, usually in a dogfight. Better boosting is still a great advantage because you can either engage or disengage on your terms, if you can permaboost faster or they can't boost all the time.
Dropping the game because it doesn't fit the way you play is a very bad reason to leave a game. Sure, it's only a game so you don't NEED a reason to stop. But that doesn't stop it being a bad reason.
ED has a problem with situational awareness, though I daresay that familiarity will lessen the gap. I frequently boost turn to try to get bead on a big ship (always an anaconda, small ships this never happens with) and then find I've just flipped right round to their front guns. Better radar or a HUD element for an off-screen target with range and relative heading would do for me. But its lack doesn't make me not play.
It's not that the game "doesn't fit the way I play". I've adapted the changed the way I play many times in my playtime in elite. Hell, trying new builds, ships, and combat styles is one of my favourite things to do. The reason I don't really play anymore is because frontier has undermined their own design, and lost sight of what made flying in elite fun and unique.
