Bard

Since they can use Ninjastrike Augs, Bards have a high level of single target DPS (a close second place to rogues, monks, and rangers)

In addition to doing a high amount of single target DPS, Bards have several other benefits:

• Epic effect "One Man Band" is a short duration, high HP group heal, with 1 minute cooldown.
• Group movement modifiers "Selo's" line of songs
• Tempest Blade line of songs (adds damaging proc to entire group)
