I have planned to do a Medieval theme for the Scout.
Hat:Jester's Hat I think this hat will go with the Scout quite well
Primary replacement:This is going to be like the force of nature but only caries 1 ammo it will be a little faster reloading and do more base damage and no knock back effects
Melee replacemen:There are going to be allot less spikes and will increase damage but you will have to (move slightly slower or the speed of swinging will be slower) I can't decide witch one yet
