I have been using the Mino in PT 9.2.0 Part 1. I wanted a ship that had a good rate of fire to keep the grinding from getting too boring. Her big firing arcs remind me of USN 152mm. But, one of my favorite ships for fun is Omaha so I am used to big arcs. I have been using RDF and its useful, but I am still in the learning process with it. The paper armor is a major problem. I try to stay at 12-14km and lob shells onto BBs that are already engaged. If I catch a DD out in the open its an easy kill. The AP only wont start fires and isnt strong enough to get many points. I wish it had HE that was capable of burning BB, CN, CL.
In one battle I fired a spread of torps at a DD. The DD changed course. I rained AP on it and it changed course again right into the torps. It was like herding cattle.
After only 3 days playing Mino I give it a big thumbs up for being a FUN ship to drive.
