Hello Commander Martin Schou!
I like the concept of limiting preparation based on rating.
It makes rating more important, which is always a good thing in my book, as well as potentially making it harder for saboteurs (they'd actually have to do some good by fortifying and undermining to increase their rating to be able to hurt the power).
I'm also attracted to the concept that preparation becomes finite; another incentive to work together if you really want the power to do well.
I do have a concern though.
Such a system would be particularly painful to powers with small supporter bases with regards to preparation competition, which tend to be smaller powers, though this isn't always the case.
If a system was desired by two powers, one with lots of supporters and one with few, this system would essentially limit the effectiveness of "putting the time in" which is currently available to small user base powers. The large user base power could offset this limit by simply sending more folk to prepare.
It's somewhat of a corner case, but it would be interesting to hear what you folk think on this issue.
One way of addressing this issue is with a Hard Cap for Materials.
Currently anyone who has the funds, and the cargo space can fast track materials to boost a system.
While not wanting to eliminate this ability, it should be hard capped on a 24 hour cycle.
Rank 1 = 100
Rank 2 = 200
Rank 3 = 300
Rank 4 = 400
Rank 5 = 500
(Or some other set number. Just using the above numbers for example purposes)
Every 24 hours, a player can pick up as many Materials as their Rank will allow with 1 Fast Track ability to double the number.
Using the above example numbers, this would allow a player at Rank 5 to truck a maximum of 1000 tons of materials in any 24 hour period. 500 for their allocation, and 500 for the 1 shot Fast Track per 24 hours.
This would have a 2 fold benefit for powers.
1. Casual Players can pick up as much tonnage as their rank allows and that they can carry, all at once, instead of having to wait 30 minutes to pick up more, then wait another 30 to pick up more. Those who have limited hours to play can maximize their game time.
2. Big Spenders would be capped, preventing them from stacking a bad system onto the Preparation List
Players who have large cargo ships with millions of credits would no longer be able to buy 800+ tons of cargo every 30 minutes to truck to a bad system, stacking the deck in favor of that system. They would be caped at a maximum of XXX tons per 24 hours.
With a Materials Cap it would be easier for the faction players to counter a bad Prep system and push it down on the list.
