We still don't really know enough about insurance costs or types to make an informed decision, which is a bit of a shame because the deadline is looming.
This is the only reasonable comment so far.
No one knows how the economics will work. All kool ade fan boys who are saying no, it not worth it are doing so from a standpoint of faith.
At the moment I get the impression that insurance is 5% of ship + equipment value. In a situation where you are trying to make a run into an anarchy and it takes 20 tries, that's your entire ships value.
If insurance does cost this much it will force you to purchase more credits to continue when pressed with hard challenges. It will be a pay to win environment, and yes the 50% insurance break would over time present a good return on investment.
That's the counter to the kool ade drinkers assertions that it's not worth it.
The fact is as yet we do not know, and do not have enough information to make an informed decision.
The question to ask is how many credits will 100 pounds buy? and how much does a equipped ship cost to insure?
We do know that combat is very arcade like, so there is a good chance that your ship will get destroyed often. If every time it does it costs you 1/20th of its value ... or maybe you need a new insurance contract every time you exit a station to make a run, if it will cost you 1/20 of your ship value every time ... just think about it.
It would be nice to know how it will work, if anyone from FD could weigh in that would be awesome.
