Why No Melds?

Ahh no there is a fundamental difference in the roles.

More damage helps everywhere 100% of the time, more HP helps how often? More damage helps everyone in the group, more HP helps yourself.

Any time you take an unavoidable AoE that would have killed you without it, either due to your bad positioning for AoE heals or the healers prioritizing other more important party members instead of the dps.
