You are allowed to read what I've written before. They put in "Action role" all skills being a basic tool for everyone sharing a same "role" and not having difference whatever is the class you are currently playing. Every tanks should get Provoke, every MCH/BRD should get Refresh (restore MP) and Tactician (restore TP). Then you can get rid of some of those basic tools to get something fitting more the current situation if you know what you're doing.
It's not devs' fault if people are bad enough to don't pick Esuna when needed, as it's not their fault people see the current system as "boo, this is not part of my class anymore, and it's not mandatory according to SE's system". You can select it, it's part of your class that's all. And I believe those who don't get Esuna when needed would not have use it anyway. I saw several fights where we died because the healers didn't cleanse the debuff. And guess what, it was part of their base kit.
So as it was before, you just have to communicate to make sure the healer you're playing with will use this spell for X or Y fight. In an MMO, improving your communication skills is as mandatory as getting Esuna.
