I whipped through a couple 4x FFA games last night and several observations come to mind:
1) The AI still builds way too many seeker mine carriers (though it IS using them to lay mines).
2) TEC mine sweepers/scouts now lack the firepower to destroy seeker mines before becoming an expanding cloud of debris. This means in essessence they can't do their job without close to a 1:1 loss ratio. I even assigned some flak and other units as protection/additional firepower but to no avail, when the TEC scout is in scanner range of the seeker mines it is also in range of the activation range of the mine. The only real effective means I've found is to drift a capital ship near the field to peel the mine field onion like. The cap can take the hits, esp with hull/shield healing nearby, it is faster at clearing mine fields than scouts.
3) The AI fixates in neutral resources, it is quite easy to provoke fleet engagements by mucking with them. The AI will persist even when I have clearly won. I can even use that technique to distract a fleet from attacking a real target within my empire.
