Meditation is not intended to be used multiple times in a direct fight. The entire point of it is to give you a way to make up for the DPS lost when a boss jumps or becomes invulnerable - NOT to be thrown into the middle of your rotation. Hit it 5 times between pulls, or make yourself a macro to have it do it for you so you don't have to hit a bunch of buttons over and over. If you're trying to use Meditate in the middle of your rotation, you're doing it wrong and losing DPS for it.

I will agree the sound is pretty grating, though. I like it but 5x between every fight not to mention tossing my form shift in as well can be a pretty loud mess before every pull. Aside from this there is nothing wrong with the skill that you can't fix with a quick macro in between pulls / phases.
