I didn't say anything of the sort... I was using an example of existing fights - neither of which you have apparently done? For example, in A3S last phase 2 people will get debuff that has to be erased within certain time or they'll die. At the same time, the tank is getting hit hard. So instead of both healers not healing the tank who is getting beaten to death, we (and to my knowledge, all the other groups doing that fight) chose to have 1 healer erase the debuffs while the other made sure the tank was kept alive. Both healers were working 100% and had their own, important responsibilities. And then there's you, without apparently any experience whatsoever from these kind of fights in this game, telling us, the healers who've actually done this content, how our playing is lazy, irresponsible and unfair. xD
What you don't understand is, in my case too, both healers are working equally hard. They just have different responsibilities and duties during each part of a fight. If 1 person gets a debuff, it makes no sense whatsoever to have two healers casting Esuna on that person at the same time. That's one whole gcd 100% wasted when it could have been used on something that's actually useful for the whole group.

What I actually said was that often in fights when there are debuffs to remove, groups give that duty to one healer - because that makes sense. I did not imply in any way that one of the healers will or should have to work harder than the other, that's your imagination (and lack of experience from these types of fights).
