That's the issue with how combat oriented D&D is. While there is a wide assortment of abilities between classes and their roles in combat, a lot of non-combat situations are reduced to just roling high on a skill check, not many choices and approaches to be made. There might be the odd utility spell, but even that isn't a choice for martial classes. Because of that, Bards dominate non-combat encounters, with Jack of all Trades and Expertise.
