Why don't they just make Eukrasian Dyskrasia spread Eukrasian Dosis?

A little off topic, but DoTs don't do damage when the boss is untargetable in most content, right? And I've heard it used to not be that way? It seems kinda silly they went out of their way to punish refreshing them right before that happens, but also go and make a job that's rewarded with a bucketload of extra damage in the same situation

IIRC it was a fix intended to not allow certain bosses dies while they're in the middle of transition or mechanics that makes them not targetable. I may be wrong about that though.

[...]The dots aren't the problem, though, it's the idea that healers shouldn't be damaging, which has reduced their rotations to 1 button for the majority of the time.

The fact that they had this idea of healer shouldn't be dpsing (preferably) but at the same time also factors healer dps into fight length's gotta be one of the most hypocritical design they've ever cooked up.
