I mean, there is animation how you draw a sword or poleaxe or whatever. Yet when we put them back, weapons magically teleport to the belt(or back). Some would see this as nitpicking but i thing its important detail. If animation would be added there no longer would be - "quickly hiding your weapon running away and quickly drawing your sword" - tactic on the battlefield. If animation would be added, player simply will be still in battle stance until the "sheathing" animation would end.
And as always sorry for bad "Engrish"
