Healers that don't want to DPS are like DPSes who refuse to move out of AoEs.

Your argument is even worse:
"It's not bad tanking, just inferior CD usage!" - Tank that doesn't want to use CDs.
"It's not bad MNK DPS, just inferior positionals!" - MNK that doesn't want to use positionals.
"It's not bad DRG DPS, just inferior combos!" - DRG that doesn't want to use Blood of the Dragon.
"It's not bad SMN DPS, just inferior DoTs!" - SMN that doesn't want to use DoTs.
"It's not bad BLM DPS, just inferior use of fire magic!" - Ice mage.
"It's not bad support, just inferior TP/MP regeneration!" - BRD/MCH that doesn't use songs/turret.

But hey, it's all optional optimization, right?

No your arguements is... more akin to...

Being in my party and telling me I was SUPPOSED to be using my Physick to heal the party with the healer... because like... I can and stuff... and its part of my job to heal everyone.

Because... like..... you're a DPS... but you know... since like Physik is a healing skill you're not really a DPS you're a healer too...

I'd be looking at you like you were an idiot.

Yes if the healer goes down and there's no one left TO do it... sure I will... but expecting me to heal everyone else because like... "its your job and stuff and properly utilizes your character because you're a healer too"... is living in your own little world.

Because that's literally what you're doing here.... to the healers

And saying if I don't heal it makes me a "bad summoner"....

You're missing the major difference here: DPSing healer is actually really powerful (capable of out-DPSing many actual DPS jobs on dungeon trash pulls alone, and two healers capable of adding raid DPS that equal to amount of an extra DD in Savage), because their design supports healer DPS, while SMN and BLM are extremely weak healers. Secondly, if you look at what's the best use of abilities in a situation (which is actually what you should base your playing at, no matter which job), in many situations using damage skills is actually the most useful choice for a healer, while it's extremely rare that using a healing spell would be the most useful choice for a BLM or SMN. Nevertheless, if there would be a situation in which casting Physick would be the optimal way to help your party as a SMN or BLM, then yes, of course you should use it! That just almost never happens, whereas for healers using damage abilities is useful in more or less all content.

Except she isn't.

Wanna know what's the difference? Healing as summoner is not efficient. DPSing as healer is efficient. And efficiency is what separates a good from a bad player.

A more correct analogy would be refusing to use resurrection as Summoner, since your res is fairly efficient. And if your healer ends up dying, you tell them to git gud instead of ressing them, because you shouldn't have to use skills outside of your role to compensate for their lack.
