On top of that, most healing in raids is AoE, so whatever periodic damage you're are taking is being taken by other members of the raid as well, and going to be healed up as a group.
I wouldn't say it's completely useless, but it's practical parameters in PvE are very narrow. To be effective, you have to be taking substantial amounts of damage, no more than every 6-10s, and not being healed externally; a combination which is very rare.
The only places it really shines are intermittent/well-kited PvP, or heavy AoE solo content.
