Poor AI

[Master Belisarius]

Yea, the AI is not bad laying mines (in fact, usually have not problems to determine the more dangerous warp points and full them with mines).
The problem with the AI is removing minefields. Some modders have included minesweepers into their attack ships as work-around, but I did not, because I like the cloaked Pyrochette ships... and the AI can't use the minesweepers with cloaked ships.
