Should've made NEMPs damage the bases too, might have deterred them from being used (Yea you can nuke an enemy fleet but at the risk of heavily damaging your base that they're seiging).
I had never seen NEMPs in use before this event either, and the couple that went off when I was present kinda went unnoticed. I heard the alarm and all, but couldnt see any enemy ship in range to actually fire it (everything was at 9+k for enemy contacts), and didnt see any projectile to avoid. That said, I think someone on our side had a shield of some sort that stopped it from killing us? Not sure how that works, this is all new mechanics to me.
