Hmm, I guess I have not beatten this to death yet.

I don’t use mines but I was wondering:
Let me guess.
A ship enters a mine field and looses all engines.
Since it has lost all engines it can’t use any remaining shields.
Since it has no shields it is easy to capture.

My question:
How much would the following cost you in resources per turn?
The Mines, (once deployed can not be used anywhere else)
The Mine Layer, (specialty ship that drains resources when not in use and will become obsolete as your fleet becomes faster)
The Repair Ship, (is a drain when not in use, granted has other uses when needed)
The fleet to protect them at the Worm Hole while capturing and repairing the ship.

I feel the resources spent on this strategy would be better spent on the best fleet you can build. This will give you:
Much greater flexibility
The ability to move all elements to where you need them.
Retro Fit for all elements
The ability to move elements to the front lines as your empire expands.
You may want to include Satellites. These can be moved when convenient.

I guess I'm just too competitive.
