General Community Resistant to Healer Damage?

[Lersayil]

And this right here is what disgusts me about the whole argument. Dead weight is someone who contributes nothing to the success of the run. AKA, someone off AFK in a corner.

Take a Healer who never casts damage spells. Run a dungeon. You finished it, right? With no complications? Right.
Now take a Healer who never casts a Heal. Run the dungeon. How far did you get? Not very far.
One of these is a dead weight. The other is a run of the mill Healer.

The entire point of a Healer is to keep the party alive. Anything you do beyond that basic task is a bonus to the party. Just like Dancers who use Shield Samba and Curing Waltz properly to lighten the load on the Healer, or a melee DPS using Feint and Bloodbath.
We don't scream at DPS for not using the more supportive buttons in their kits. We encourage their use, sure. But never to the disturbing degree that Healers get shat on over DPS.

A Healer who never damages is just as effective for the party in their primary role as a Healer who is comfortable and capable of pushing damage between Heals. If they weren't there to Heal you, You would be dead.

We should be encouraging people to find openings to do damage, not shoving the "MUST DO MAX DEEPS OR BOOT" mentality down their throats.

To be fair to both sides... it would be more correct to say that they are being a deadweight 60% of the instance (if we estimate a 40% healing uptime, and I'm being generous if we assume lvl80).

Might not qualify for the label of "deadweight", but if a DPS or tank only did stuff 40% of the time in a duty, I would most certainly call them bad at their job.
