With SC we still have the vague statement by The Roberts that the insurance we get as part of the LTI feature will only have a minor impact on the game, since the "legit" insurance of that level would be rather cheap. He stressed that it would not be a balance breaking amount of credits. Make of that what you will.
Not claiming that the LTI won't cause balance problems, mind you. Due to the vastly different schedules I'm still keeping mum about SC. Elite is close to being released, SC will come whenever. Expect a bit of angry noises from me once SC enters the last stretch with LTI issues and whatnot.
Example: If an Elite alpha player can afford an Anaconda and save ~
175k credits on his insurance, then that's quite a bit of moola he can invest in weaponry or freight that an ordinary player cannot hope to match given the same amount of playtime and money.
Worse yet, as ships (and by extension, insurance fees) grow more expensive, a blanket insurance rebate based on percentages will impact the game more strongly as time goes on.
SC has avoided this particular pitfall completely. Sure, a bunch of lucky backers may hit the jackpot and grab a hold of an overpowered hull, but they just need to release a new model with better specs to fix that. LTI will only ever give you the hull you pledged for, not a more modern revision. Eventually, I expect all LTI hulls to underperform due to power creep. At that point, they are able to futz around with insurance rates all they want to balance the game.
Elite can't do shit about their version of LTI. They have given a no-holds-barred indefinite rebate that effectively gimps insurance rates as a means of money flow control. The higher insurance rates go, the more alpha and beta backers benefit, thus giving them a tangible edge. The lower they go, the less money they remove from the game and the more likely the players will engage in unsavoury tactics (kamikaze attacks etc). No easy way out of this particular problem, so they can only keep it in the middle and try to affect the market with other means, such as docking fees, taxes, or inflation.
