Now that our starbase has hit Tier 3 engineering, I was excited to buy advanced fleet weapons. But I think I may have found an oversight -- there are no advanced fleet transphasic mines! The torpedos are there, and mines of every other variety are also included. Alas the transphasic mines are conspicuously absent. I know it's not an issue of them being too powerful, since I can buy advanced fleet tricobalt mines.
So please make sure to add them into holodeck soon!
Fleet mines are a complete waste of time as they all have DMG on which does not work with mines.
I'm not sure what your reasoning behind that is. If you simply look at a mine without DMG versus a mine with DMGx3 you'll see the stats are affected. Also if you look on the exchange that DMGx3 is the most expensive option you can buy when it comes to mines.... so yeah, I'd say there is a difference.
And in case you were wondering, the consoles DO affect mine damage as well.
