Honestly, I think you should be able to throw your main weapon. Not all weapons, like danish, great sword, flammy, great long axe... etc, but being able to throw your polearms, (mainly spears,) and 1handers, and such. Would be awesome.
And being able to retrieve them on fallen enemies, or allies, but only if they're dead.
Idk... what do I know... (nothin.) Just an opinion.
EDIT: Being able to grab your enemies is retarded. DO NOT implement that shit. ;]
