Actually it depends: In leveling dungeons, especially when it's a sprout tank i try not to let them drop below 50% - while not overhealing. I can sympathize with tanks that get a bit nervous when they're at 10% constantly (like i felt when i started as tank) - in raids... that's a different story.
Just to add to the discussion from before. While i know it's anecdotal, and the FF14 comm has its bad apples on its own, the last weeks low level content not only got filled with more sprouts, but it seems to me that they're getting more aggressive.
Just yesterday i had a group of 3 sprouts. They're all eating vul stacks at the boss (each of them at 3) and are ignoring all mechanics. 2nd boss in doma. No one is moving into the pillars - i have extreme problems keeping the group alive (bonus group damage on vul stacks). Next time i grab one of the dps into one of the zones while heading into the other - he runs out, and i barely manage to keep the group alive.
I mention after the boss "Next time please move into the pillars, i cannot heal all this damage" and i get as an answer:
"Don't whine. I'm carrying this fkn group, so shut up and do your job." (now i'm leaving aside the irony of a 67 blm with crap gear carrying anything)
Honestly, i haven't encountered such hostility in 3 years in FF14, but i played another MMO where i saw something like this a lot. I'm not one of these good community fanatics, because lets face it, people are asshats everywhere, they're just more friendly in ff14 because the repercussions are more direct, but at least in my subjective view i encounter a lot more of these people in recent weeks.
Well, the good thing is: I now know at first hand that SE are really very fast in answering their tickets
