And it's not like this idea only came into vogue after 4e published the Warlord. There have been LOTS of threads about people wanting to make "craven" characters or "intentionally bad at combat" characters. The Lazylord concept--which 4e never officially supported, unlike what most people think, it just happened to be an emergent possibility as the edition evolved--enables players to do that. Not only does it do so, but (at least in theory) it allows a character with any chosen mental stat to function as a thematically-useless but mechanically-useful character. You can have the aged gentleman-squire who's too old to fight but is really good at outwitting opponents and improving his allies' efforts, the canny street urchin who's too young to be a real fighter but is resourceful and incredibly observant, and the Disney Princess who inspires others to action through her winsome ways but would never hurt a fly.
