I actually DID play the Rogue. Was out done in skills by a Bard, outdone in battle by the Barbarian, and really DO feel like the Rogue isn't that impressive...BUT I DID give it a shake.
Maybe I just don't understand exactly what the Rogue's speciality is supposed to be in D&D next.
My take on it would be that the Bard is good at both skills and spellcasting, while the Rogue is good at both skills and combat. A focused spellcaster (like the Wizard) will be better with spells than the bard, while a focused combatant (like the Barbarian) will be better at combat than the rogue.
But, in return, the bard and rogue have their improved skill use and utility features to give them a solid role in the party.
When compared against each other, meanwhile, the bard has the bonus of spells, vs the rogue's greater capability in combat.
I wouldn't think that the bard would be better at skills than the rogue. I suppose it could be the case that in the specific adventure you played, the bard's skills and abilities happened to be more relevant to the situation, but I think that tends to balance itself out over the course of time.
