It works pretty well. With the armor skills there's plenty of armor on the legs. Adjust accordingly if you are short skilled.
For some reason I can't open the new loyalty mechs in Smurfy. Running the same loadout on a cataphract, which is a bit faster and just as tanky. The ST hardpoints of the victor are probably better though
4/5, I tried this - it works or course, but it is what some other 70-85 tonners can run, so I did not feel special
