darkbard - if we had constructive threads about useful techniques, then where would we find the time to argue that metagaming is not really RPGing!

Garthanos - I don't think it would break the game to identify ways for fighters to have strong INT- or CHA-based skills. But I don't hae any suggestions on how to change the system to allow this.
But as the game is currently structured, here is my take: recognising the heraldry of the local realm, or making friends with a town mayor, is Heroic tier or perhaps low Paragon tier activity, and a fighter (especially with training) can be as effective at this as a bard, warlord or wizard.
