The other extreme

[Gemina]

I see this as a matter of players need to trust their healers and let them do what they do. A knowledgeable healer is always assessing how quickly the damage is coming and adjusts their threshold for healing accordingly. If the healer feels there is no immediate risk of a KO, then the DPS window remains open. Over-healing may not necessarily be a sign of a bad healer; it actually can be more indicative that your healer doesn't trust their group.

My rule of thumb for DPS players is that they have enough health to survive a hit. They have lower HP pools than the tank, so single cures restore a greater percentage of their health, and it actually irks me a little bit if I actually have to use a cure spell on a DPS player outside of scripted damage they take. Regens and fairy should be enough to keep them up.

Tanks are a different story. The over-geared ones have such ridiculous health pools, and take so little damage that keeping them at 40-50% really isn't much different than keeping them at 90-95%. This changes obviously depending on how well the tank is geared and content played. Sub par tanks need constant healing, and a healer doing their job will remain out of Cleric to do so.

Haha! This is so true.
I recall one day a mate being like "It's fun to do dungeon with you, I always have a shield and Stoneskin on"
I was like "yeah, don't worry I got ya!". But the Truth was that he was so bad at dodging that I had to keep shield + stoneskin. *cought* BLM *cough*

BLMs do not move. Healers adjust!

BLMs are the one job I can accept standing in stuff tbh

Sometimes I even encourage it, tbh. A good example is the second boss of Gubal HM, which does the Eruption-like AoEs that chase you down like four times. If I have a caster in the party I'll either give them a buffed Regen or Adlo them+ cast Whispering Dawn to keep them from moving. Always gotta guess if they'll take the chance or not, tho.

Ohh I hope I don't lose my precious stoneskin! It was always entertaining for me to see which DPS player can keep there's up the longest. Some would literally keep it up until scripted damage strips it from them. Others would drop immediately into the first pull, and I'm like "really?!" Ugh, I am such a stereotypical WHM.

I also don't ever tell any player, friend or otherwise, "I got you". This my friend, is a death sentence if it comes from me -
