For me, engineers ruined the game. I haven't played for any significant amount of time since they were released. I'd still love to come back to Elite but I'm too salty about engineers 
Around the same time as they released engineers they rebalanced PvE, so now you basically have to do a pain-in-the-butt grind / mini-game with an SRV, with horrible controls/responsivenes and a terrible scanner, to even get the mats for Engineers. They completely ruined the play-your-way ethos as soon as they added them. Now, if you could get the materials as a by-product of trading, or bounty hunting, or exploring (i.e. any of the established professions) then it wouldn't be so bad. As it is I have no desire to drive an SRV, so I have no desire to play.
Unless someone can tell me things have changed? ^^
