Like in the mod mount&musket there are quite loads of "useless" things to do for example you can play the piano in the map or flute or wind-pipes etc.. and you can do the surrender animation if you drop your weapon.
Some animations such as sitting down wouldn't help in the combat of course but it adds more fun in role-playing for example if we are watching a tournament we can actually sit and watch instead of all standing there.. or adding some playable music instruments would be cool as well~ sometimes you just get tired fighting and want to do something pointless but relaxable all i can do now is building stairway to heaven in duel servers or play with a torch...
just a suggestion :d surely will add more fun into crpg
