What is this new anti dps healer attitude?

[Ferrasper]

This is only true at the lower levels of Stormblood. Im sitting on 1300-1400 piety on my lvl 70 ast. But even before, it was a bit tough on MP but still entirely possible.

I would rather be safe then sorry. When I have to constantly use Mana Shift on the healer taking away from my DPS, I would consider that a bad thing.
