I was wondering if any of the neutrals, like the militia or pirates would use mines on their wells. it's certainly not something you'd want for fast mp, but in a sp game where you are under less constraint it might be interesting if you had to bring a scout to new wells too, so as not to get trashed. it would make sense for neutrals to employ means to kill intruders. just so the build up is a bit more dynamic and less of a rush to get planets and fleet.
though that also goes in the area of neutral player improvement and such, so it may be planned in the 2nd pack.
