I posted this on r/eve a few months ago. Figured I should re-post it here for critique.
Increase the base vulnerability time on Upwell structures;
- 4x for M-Size
- 3x for L-Size
- 2x for X-Size
Add a Service/Module that configurably reduces vulnerability in hourly chunks - down to the original vulnerability times. Set hourly fuel cost to be equal to the total number of hours reduced.
Example:
If you want to reduce the vuln. of your Raitaru by one hour per week, your structure consumes 1 * 24 * 7 blocks each week to do so.
If your want to reduce your Keepstar’s vuln. period from 42 hours down to 21 hours, be prepared to depart with 21 * 24 * 7 blocks. If you have a Keepstar, you can afford a measly ~88M ISK/weekly in its upkeep.
No structure ends up being safer than before. If someone wants to maintain the same level of safety without putting bodies on-grid, they pay in fuel. An unfuelled, undefended structure is now much easy to dispose of. Unguarded Astrahausen are no-longer safe because their timers are set to right before DT on Wednesday.
And an addendum: Re-kajigger the cost of Upwell stuff slightly to account for the purchase of this new Service Module. All existing Upwell stuffs get given a freebie installed on patch-day.
