The thing that bugs me about their parser stance isn't really the "harrassing players for bad DPS" type deal, because while I disagree with that I can at least somewhat understand them not wanting the community so meter-focused that they shun classes over it.
What actually bothers me is that if there is a real problem, exaggerated or not (like WAR pre 2.1), we won't be able to use aggregate meters to display that. Things like WoL are pretty important for things like that in WoW and help add more objective numbers to a complaint when the community feels there might be a problem with the class, and if that isn't there and we have to leave the devs to come up to their own conclusions based one whatever...well, I'm not so sure that will turn out for the best down the line.
I think the class balance right now is decent enough though.
