Personally I recommend you try the costume approach. Based on the situation of the siege or battle you can dress up like a nobleman/king/queen, generic pike/spearman, maceman, anonymous peasant conscript, barbarian peasant, winged helmet w/nudity or what not. Black robes and other combinations can make for hours of fun.
Caution however, this is indended only for people who don't play super cereal. Trust me armor and weapons don't entirely make the player. Take your time learning from an opponent, understanding how people move, and trying to fake or counter what they do. I myself am not a melee expert by far, but it can be a fun challenge trying to take down a tin can.
