As for the CT metagame issues, well presumably you've already done away with the single most effective one, death in character generation.
This is I think one of the most misunderstood balance rules there is in CT. I remember fondly the effect death had on limiting the careers of characters. There was a very real sense of acheivement in living to retire from the Navy with a pension, or gambling that your career as a Merchant was long enough to earn you a nearly paid off ship if you were lucky. And then there was the fear of that enforced callback when you had decided you'd pushed your luck far enough as a Marine and decided to muster early.
Worried about aging rolls? Hardly ever. Most of the time we got out of the career before we had to worry about aging, we were afraid of dying! The game (and the game within it) lost a lot of it's punch when the decision was made to make death in character generation an option rule and most of us blindly adopted it as the best way since it was the suggestion of the powers that be. Who were we (mere players and young) to question the intent of the (presumably older and more experienced) designer(s) of the game.
Did it speed up character generation? Yes, but then creating a CT character didn't take long anyway.
Did it make it better? In retrospect and with the experience I at least attributed to the designers when they suggested it, NO!
In my not so humbly suggested opinion the game lost more than it gained with that one ruling and I've not encountered anyone else who feels this way. But maybe that's because we have kept quiet about it. Perhaps by speaking out I'll find others who have secretly kept the same opinion, or maybe even win some converts over to my perspective. But of course, it is just an opinion, shared or not, it may not suit you, so as ever, YMMV and do as you please
