That has never happened. Likewise, most Bards never use their Song skills, and nobody uses their self-healing skills. It's rather silly to think that the Healer should be contributing to DPS while the rest of the party does nothing to help heal themselves or... avoid taking damage entirely.

If the Healer "has to" DPS, then that is a tactless admission that you think the DPS are not pulling their weight. If a DPS casts Cure/Physick on another player, that's the DPS tactlessly admitting they think the Healer is awful. Similar statements can be made about players casting Stone Skin or Protect that aren't the healer. (Keeping in mind that it's not available to CNJ/WHM before level 34)

So what you're saying is that "because others are playing half assed, you should play half assed". Excellent advice, I think?

Also, the contrary of whatever you claim can be made as well:
Bards never use their song skills -> bards actually do use their songs when needed
Nobody uses self-healing skills -> Warriors use these all the time. Whenever a DPS player uses them they simply go unnoticed or become pure overheal (Bloodbath primarily)
Rest of the party does nothing to help -> There are parties out there who actually do. Even if not the entire party does it as whole, some of them do.
Healer dps never made a difference -> party wipe at <5% because neither healer did any form of damage
Healer dps never made a difference part 2 -> push phases quicker which would save both healers MP. T12 being the prime example
Healer dps never made a difference part 3 -> Even in content like CT, ST and WoD. ST being killing crazy dog lady, Rugby-man and phantom of the opera guy before their final mechanic happens. Effectively saving everyone several minutes, especially on the rugby guy.

Everything you cram out is extremely subjective and one-sided. In the other topic you even acted as if you made this game yourself. 3% damage contribution? 25% of a dps class? Have you even set foot in the other half of the game yet? Of course a healer can only contribute 3% of the total damage in Crystal Tower. That's simply because of the sheer number of people there. Everyone's share gets smaller. Present some facts to support those claims before making them.
