How bad can it be if there is overheal? Is this somekind of practice tools?Let them be at peace with their paranoia.

I fail to understand becoz i rarely see this except in raids or trials when there are 2 healers. New healers mostly just stand there doing nothing if none to heal
Some healer just don't care or don't know, never play healer in other games where agro management meant everything in dungeon, how i miss this element in ffxiv dungeons... The fear of overheal

With simplified mechanics for tanks to control agro, I don't see this can be a huge problem anymore. We also lost our enmity reduce kit becoz its not needed anymore. So this tools have lost its significance
Except it affect the healer mana management and dps output

For me i heal base on health percentage, choose which spell base on it
Crit heal will always have some extent of overheal, can't really control it
I always excog tank before pulls, sometimes it pops on timer end, cant be help but it one of the way that i use to fill faerie gauge
For now its a waste of resource for dev to address this, let them fix other healer issues
