Let's redefine "damage taxes"

[CKNovel]

More often than not, even in a downtime situation, you're most likely to either step on your healers' toes or not contribute to the HPS in a meaningful way. In most DSR downtime you're sitting close enough that the healers, also freed up to use GCDs, handle it all well enough anyway that vercure is redundant at best. At worst, your vercure topped up the DRG that your WHM was gonna farm a lily off of, or your SGE was gonna do their thing to for Toxicon, and you ruined or inconvenienced their plan to have Misery/Toxicon ready to go when Thordan is back.

That argument can be said the same about... Everything.
During the Natural alignment, 2 party member are targeted by a beefy dot. As tanks we assist the healers, my co-tank DRK uses TBN and I Corundum+Aurora. Yet it happens that I throw Aurora and the next second that party member is topped with a TBN as a shield. Regardless of jobs, you will inevitably screw someone.
The same can be said with DNC healing.

That's how you must see those healing tools, as a neat bonus.
And I believe that's how the raise should also be seen, a neat bonus.
