It's hard to tell if this is a bug or mines proximity and so on being changed.
Now normally mines need to activate do they not?
What I'm seeing is mines being dropped and every single mine instant pops. They don't go through an activation and they don't even start moving. It all happens very quickly and I've been playing STO PvP since the game came out so I know the usual.
It's like the entire cluster of mines is instantly applied to my ship and scoring immense instant damage taking my Atrox from 100% to 12% in PvP there just now.
The players who are doing it are from fleets who practically advertise their keen use of exploits.
