Haha this is something we've considered. Skill names in OSRS are weird and don't follow consistent grammatical rules. Even "Runecrafting" is actually just "Runecraft," but using the verb form is so dominant and flows nicely with a lot of other skills (Mining, Smithing, Woodcutting, etc) that most people don't even realize it!
So we've settled on simple "Bard." Maybe not the most conducive to being verb-ified as Runecraft or Attack, but we wouldn't want to confuse it with real life barding!
I dunno man, horses ain’t real :P
