Baisicly, the ability to define a level of resources (like the share lines) that should never be used by production and repair. Once this level of reasources is hit, no more reasources should be taken for construction, repair, resserection or capture costs. The only thing that would drain resources would be weapons, power upkeeps (like shields or radar) and Dgun (or similar special abilities).This specificly allows for several things:
1. Energy reserves for laser and plasma weapons so that you can always fire (unless your power is SERIOUSLY hurting. This also includes Dguning of course
2. Resource reserves in case of needs for emergancy building/sharing with allies
How difficult would this be to impliment?
