Bard Melee and Instrument Swapping?

[AlgebraTheBard]

I mained a bard in live server before LoDN, I would say a bard benefiting the group with our songs than our crappy melee output, since we can keep at most 5 songs running (assuming a melee/caster balanced group) - haste, slow, snare DoT/CC, regen, mana song. However, I seldom swap instruments cause of the comparably short fight time.

and I always stand between melees and casters, so mana song hits most members.
