I don't see the confusion but let me dumb it down for you. Subverters disable everything within a certain radius. The affected ships can't move, shoot or do anything. This enables the mine layers to lay their mines without them being destroyed. The only things that can destroy them is cap, SB or strike craft when this happens(something that is not disabled by the subverter). This makes it less likely that the mines will be destroyed by what you are trying to use it on. Assuming you have strike craft to do so, you can still destroy the mines but at a lot less risk seeing as how most firepower will be locked up with the subverter.
Now with advent, mines are strike craft so they are vulnerable even before built if left undocked. To do as you say with advent homing mines, one has to lay mines and afterwards repulse the enemy into them. The frigates and strike craft etc are still active and able to fire. Now this does not matter as much assailants and other forward shooting ships unless you give them enough time to turn and shoot or some are not facing the same directions. With flak this does not matter however because of the 360 degree firing arc and the fact that the flak can shoot them down as they are flying over to be laid. The strike craft can still kill after they are laid but they have the benefit of being able to do it before its done as well. This leaves a wider opportunity and more possible combatants to shoot down the mines rendering your strategy useless and less the money you spent on them. Did I explain it well enough for you?
This is not real life and comparing real life to a game gets you nowhere. If you use mines offensively, they are called bombs. Mines by nature are passive and only triggered by encroachment of presumeably the enemy but pretty much anyone that comes close enough to trigger it.
If this is an attempt to bust my balls about your "strongest lrf" thread, then try again. I am not the one that started a thread about a test and not show a replay to back yourself up and demonstrate methodology of your test.

MINES are a type of BOMBS. I dont argue to make all mines move and seek to destroy fleets
Lets see if I can dumb advent mine laying for you.
Guardians repulse entire fleet preventing them from attacking and cripples movement
Advent undocks mines and lays them behind fleet (dont be dumb and fly to enemy flak or sc when deploying)
Fleet cant turn around fast enough to kill mines before the become cloaked and active
2nd Guardian repulse fleet to mines
Hey look repulse affects Capital ships too
Plus you dont have to use mines with repulse. Just lay them in front of you and hide in them. Mines can be effective against spammers early in the game
Again advent mines move as fast as SC and are the least prioritized target
Grey you dont use mines in combat. Why bother offering suggestions on fixes or modification. I try to balance the game as a whole unlike you,who lobby for the sole race that you only play or remove any aspects of game play you dont use.
