Which class when played with skill affects your group the most?

[isoka]

Those who don't see why bard isn't the obvious answer clearly didn't get to group with a well played bard. The moment you encounter one of those very few truly amazing bards, you will know it.

A well played bard is not just about keeping 5 songs up at all time. It's how it adapts to every situation in a fluent way while providing as much benefit songs as possible. Having only 8 songs in stock and having to manage targets make it very hard to shine as a bard.
