I'm confused by some of the logic of the anti-melders.

If you feel that a 10% throughput increase that takes under 5 minutes to setup is a 'waste of time', do you think that all other forms of gear progression are a waste of time as well?

Do you simply get to level 80 and completely stop attempting to increase your character power? Acquiring tome gear, 24man gear or relic weapons all take a significantly higher time investment than melding.

If you're willing to participate in any of the above systems to progress your character, why would you draw the line at melding?
