Rextard i agree with you, remain silent while moving is a skill, be silent while moving with plate armor is impossible.
But who said that we fight in a silent area? we are on a battlefield, there is noise everywhere, ppl fightiing, ppl shouting, ppl dying, cav, teammate with plate armor, etc.
I don't say that it's a bad idea but i'm not sure that it will fit with this type of game, it's a battle not a blackops operation.
I can't imagine the noise at spawn, i should turn off sound the first 30sec of each round.
if ppl are too unaware then they deserve to die on a battlefield, i don't speak only of archers, infantry aswell.
ps : i wear tribal outfit and leatherboots almost everytime.
