@nerthos People were always surprised when I moonlit as a HEMA instructors (years ago before that knee what I no longer really have got fucked up) that we gave as much instruction on the wearing and movement in armour as we did actual weapons training.  But if you read arms manuals from the late medieval period which we have preserved and also the Renaissance, it was considered just as important as actual weapons skill, and with good reason.  A more mobile opponent is a more dangerous opponent.
