Perhaps make a "sweeping tech" that requires Mines 1. What it will do is give copies of the PDCs that have the sweeping ability. So, without it, you have PDC I-V without sweeping. With it, you get PDC I-V with sweeping. Otherwise, the impending uselessness of mines happens a lot earlier in the game, as it will be much cheaper to research. That, or just use the normal Mines tech as the tech grid, so Point Defense Weapons 1-5 give PDC I-V. Point Defense Weapons 1 + Mines 1 gives PDC I with sweeping. Point Defense Weapons 2 + Mines 2 gives PDC II with sweeping, and so on. This could get complicated though. It is up to you really, as it is your mod.

This is good stuff, thank you Fyron
