On player hand, you can play him a bit different, but like if i need to play with it, i prefer a layout like that:
Beat a onslaught or any vanilla capital except the paragon where this is more a draw (but against a paragon, any 1v1 are often a draw).
Because of the 1v1, ennemi do not engage too near the Minster, so it cannot use the shipsystem.
On a fleet, it is very good too.
But for others peoples who use it, they just put beam everywhere. A disco ball. This is a paragon with ATC and massive amount of tactical laser. Can be seen bad, but after, when you think to it, you do not run the Minster alone without a army.
