Feeling useless in Hard mode!

You guys want us to be meat-shields? Then make us meatshields, not a paper soldier

Well said.
Knights have heaps of survivability already because of their horse and archers have quite a lot as well because of their athletics.
Commando's currently have least durability, which doesn't quite make sense. Of course, they can be shielders better than anyone else, but that rarely/never gives them an opportunity to swing back.
