don't remove re-buy, just make it not automatic... i like eve's implementation, with the caveat that with engineer mods, requiring a player to re-roll all those mods would create a HUGE outcry.. so my proposal, is you get blown up, you get to re-buy your ship. once you do, you have to pay for insurance, and you can choose the level of insurance, but it expires at some point. (maybe make that a variable too)... best part, is the more often you blow up, the more expensive insurance gets. then have multiple insurance agencies throughout the galaxy... might have to travel a bit to get better insurance rates because you're known around one area to get blown up for no good reason. heck, go crazy with it... each company covers different events.. one company charges more, but specifically covers CZ's, while others, who are cheaper, specifically don't... so, CZ's, res sites by risk level, unident signals (might be able to get coverage for distress signals, but not for weapons fire detected).. dunno, it's just an idea.
again though, engineers mods, since they weren't destroyed in the original implementation, you're not going to be able to destroy them now without massive blowback
heh, i can see it now..
guy1: hey, lets go do some Combat zones!
guy2: i can't, this ship doesn't have CZ insurance
guy1: ... idiot
