I have 8 mediums in my current team... but several are pretty lackluster skill wise. One has move speed skill which I don't need it going ahead of my heavy tank and another has a armor buff... why? Still have 3 star light tank to get rid of too.

I have 3 4star destroyers but 2 of them I use for scouting since I don't like their designs. And the one I am using costs 5 gears to spawn, so slightly annoying.
