strawman arguments.... again ditching out any possibility of debate even though :
There are a bunch of SB interviews in which YoshiP clearly states that he and his team do not like healer focusing too much on DPS. They did remove the stance dance to make it easier for those who wanted, but clearly double pointed out that it was not mandatory.
I'll try with an analogy : won't be sure if it'll fit in, but that will give you the general idea.
Cars can easily go faster than 55mph. If you want to be efficient with your car, you better drive it at 70mph, since it can go that fast. State patrol could arrest you if you went above 55mph, but who cares, they're never watching, and actually won't even say a thing if they do happen to catch you speeding. Hell, even state patrol is driving way above 70mph... So it's a common thing for everybody to be driving at 70mph on that 55mph road. Then, you encounter someone who is driving at 55 mph... because there was that one sign that was saying so : would that be considered as bad driving ?
If you happen to stop that driver and start arguing with him, it will be the same thing as in this thread.
You didn't understand what I consider selfish.
Asking a player politely to try doing some DPS is OK. I am for any constructive behaviour in this game.
But the way some people here are belittling others, or automatically making the assumption that pure healer are bad healers will only fuel the hate. And in the end, you get that feeling that those rude people only ask lots from others for their own benefit. I mean I don't know how to explain it better, even those kind of situations are pretty common IRL, doesn't only happen in games... In my country, we call those people sharks : ready to destroy or pressure anybody just so they get their promotion or extra-bonus...
This is the selfishness I am talking about.
Now why would some pro DPS try so hard to make pure healer do some DPS to the point of belittling them ?
I cannot find any other reason than this one...
edit for Tridus
As a former web-dev, I also know that you cannot listen to your customer every dreams and wishes as your project might very well fall to the ground.
Specs were defined : stick to it. It is even sometimes your job to impose your decision on what can be done and what must be done, no matter what the customer may say.
And in a project of the scale of FFXIV, you cannot rely only on the top tier suggestions as they are a minority in the game (in any game actually).
Look who won in wow... was it the hardcore raiders ?
Also, SB was definitely tuned for zero healer DPS : YoshiP's interview by Mr Happy.
So I am in no way imagining things or speaking in their stand : they actually did say it and even wanted to make sure that people knew it was their point.
The 2nd community would then be the pure healer group standing behind YoshiP and his team.
Finally, I am only talking about DF - though even for savage fights, healer DPS isn't mandatory. I can't find the interview again, but YoshiP explained that to determine the health pool of savage bosses, they would take the mean performance of all tank and dps in the superior tier and lower that by 10-15%. I actually think this was part of his explanation of why healer DPS really wasn't mandatory as it wasn't even taken into account in the tuning of the fight. This also explain why top tier group manage to push bosses and skip phases...
FFXIV, unlike Wow, do not push the players too far. They want to give players some challenging content, but also want people to be able to enjoy all the content while not necessarily being a hardcore raider.
But then most savage fights are formed through PF - in which clear rules are stated by players - and valid in this case. So in this case there is no complaining possible from anti-DPS.
