The above analysis should really only be done if there's at least some sort of math done to calculate the dps loss of a tp starved melee class.

Assuming dps loss of 30, your conclusion will be "ehhh the dps loss minimal, off with the bards!!".
Assuming dps loss of 150, your conclusion will be "that's alot of dps loss, bards are important!!".

So any math savvy min-maxing hardcore mathematician wanna help to calculate the theoretical dps loss over a 10 min fight for melee dpsers?
