I've had an idea that might be a simple remedy to the current arguements without the use of cumbersome spreadsheets and maths.
My idea is a new rule that forces all players to build sufficent tenders and support craft.
Every ship class would be treated seperately; eg two tenders per eight destroyers, one tender per eight submarines, one tender per battleship. This would also include tankers in some form. Every qaurter 10% of the standard tonnage of all the tenders added together is paid in warship materials to simulate the use of resources etc. In a war if any support craft are sunk then fighting value points are knocked off the warships it supports.
Key points are, it fills up slip spaces and takes valuable warship materials to build thus slowing down the aqcusition of warships and any future construction requires the building of more tenders.
It's simple and effective with little calculation needed, as the tenders are built the effects culminate to sim enough useage of parts and oil.
What needs working on is the sizes and displacements, sub tenders are quite large while destroyer tenders could be smaller, each type must be assessed seperatley and the tonnages agreed by a Gentleman's agreement which all players stick to. A 10ton tender would be frowned upon!
What do you guys think? A germ of a brilliant idea or have I been exposed to too many X-Rays at work!
