I believe everyone is aware of Bard's classification as "Support" but their distinct lack of any form of party healing. The distinct pulling of this class in two different directions is kind of annoying. On one hand, they are DPS, on the other, they are limited to support with their limit breaks. So I want to put forward this idea. Take the musical idea to its limits by introducing new weapons, Harps. It's been done in previous Final Fantasies. While being weak, they aren't meant for DPS. Keep the songs for Bards, but change Mage's Ballad to consume TP instead (A counter product to Army's Paeon) and provide Bards with an AOE ticking heal song (something weak, like 50 or 25 potency) and a stronger single target healing spell (300 heal potency). This allows them to AOE heal weaker than a White Mage, but single target heal on par with a White Mage. However, keep the limit of one song up at a time. So they are balanced by having to choose between group healing or MP recovery.
