I thought Yoshi wants healer to focus on healing only..

Actually that is precisely why "Get gud" applies. Bleeding edge content with minimal gear will take the full party doing everything possible to clear.

The problem isn't in the bleeding edge content, its in the normal day to day content. Which is pretty easy to surpass that bare minimum clear threshold to where the healers dps should not be necessary, yet if you go browse the tales from the DF thread you will find plenty of examples of groups that struggle to hit that point and the only real reason they clear is most dungeon bosses don't have an enrage+wipe mechanic. One of my personal favorite examples is a group that had Aenc Thon transform twice.

I'm not talking about DF PUG crap where we all realize the Black Mage has been spamming B1, and nothing else. I'm talking about the savage content.
If you want to rag, and kick all the horrible DPS in the normal mode content, be my guest, because I certainly hate dealing with tanks that don't use cooldowns, DPS that don't AOE - or have a rotation at level 80, and also healers that don't DPS.

Like it or not - healers need to DPS for the endgame content.

And if you want a breakdown of what I mean:

12,000DPS from each DPS class
7,000DPS from each tank class
6,000DPS from each healer class

That's the minimum requirement to make it through E4S enrage, with some give being the DPS spread differently. MINIMUM.
