The Infantry Problem 2

[Lophorius]

remove wall cades and replace them by something else, like e.g. the smithy to improve items if you really want to make inf more viable.
and as terror already mentioned, your assumption that inf is there to tank is (sadly) only appliable in normal or hard mode (if you've got good equipment) , however you're dead pretty quickly in rag no matter how many red armour pieces you got
also, make the 1h weapons for inf longer.
