Anyway, one more time, if you believe reducing the insurance cost at CZs (and I am only talking about CZ)would impact the game, please clarify and let us know your points?
To me I still believe it would bring more cmdrs to do CZs in open play instead of solo, which would be great for the community goals.
It sounds more like just trying to arrange an arena combat zone to me personally. What's the in-game logic here? Factions subsidize rebuy costs?
Honestly I don't think it would encourage anyone to fight to the death - there's still the inconvenience of getting back in your ship and flying back to the CZ. As I mentioned earlier, a number of people who jump out are doing so so they can jump back in via the shield/supercruise exploit. I don't see lowering insurance cost fixing that.
What you have to ask yourself is how gameplay will change when that exploit is fixed? Once those guys jump out, having to wait for their shields to recharge before they can go back in (and they can't even see on their screen if the HUD if the shields are recharged yet) maybe they'd be more likely to stay in the fight and run in real space till they charge, or be willing to risk some hull damage, etc...
It might be fixing that exploit will do more for CZs than cheaper re-buys.
