The problem with Parsers is that certain jobs will absolutely do more dps than others given different situations. It's not right if the introduction of a parser leads to players forcing out certain classes because god forbid they can't do as much damage as a Monk with a stationary target. No, in fact I'm pretty sure that the introduction of an in-client Parser will only lead to arguments over players who aren't putting out the numbers. There's a reason why Bards can't do the same damage as a Monk and honestly, I'd be appalled if they changed the game so that they could.
