Then use scouts?
"Admiral, scouts indicate a heavy minefield with SMAC support ahead. Shall we look for other rou-"
"ARR! FULL SPEED AHEAD YE SCURVY SPACE DOGS"
This doesn't happen in real life.
*Sends in 50+ prowlers to clear out a wall (and I mean a literal wall blocking an entire entrance area of a gravity well). The prowlers take out 10 of the possible 150 mines before they are all wiped out.* Oh, that seems fair to me.
Giving prowlers the ability to drop them seems more canon then just throwing them around it space. It seems a lot more of a practical use. And if it were "real life" then the ships would just jump far away from the mines if they knew they were there, but since sins restricts their lateral movement somewhat that doesn't happen.
