Yes. Why would I want to be so self centered as a healer by looking at my own character if it isn't directly related to saying out of range of aoe attacks but still in range of curing? In both small parties and large alliances, there is not actual benefit for a WHM or any healer to be paying attention to the battle animation, especially when things start to lag. It's not like driving or what melee have to do where they're looking at the on screen actions and text log. Most of the time they don't have time to look at even their own HP if they feel uncomfortable with failing healing support. You may hate it, but the rest of us who do it more than others understood that when we got into that role. Our focus IS the watching everyone's HP and the chat log. No amount of visual graphics is going to help you anyway if you're staying outside of 20' yalm range of most aoe doom spells anyway. And I, personally, get fairly dizzy and admittedly confused when I'm looking at what's going on the battle field while trying to keep up with curing ailments and healing... so I speak for myself on that one. I don't like loosing my focus.
It's a good ideal, but it is, as said, redundant. As I said before, it doesn't matter how much time you have on doom. A good healer will keep spamming cursna until they see that it's been cured of the affliction, even more so if they see some one still spamming holy waters as any person fighting a creature that can doom should have anyway, just like mages should carry echo drops. If you can't simply type "doom" then you're screwed from the beginning. And if you're not directly engaging a monster that uses doom attacks, you should be staying out of range or else you deserve to die.
That's not being mean, that's speaking truth. You have to know how to cover your own butt, limitations or not. There's no excuse for not communicating your afflictions, even if it's just one word of the affliction or the cure. Doom, viruna, silence, silena, sleep, zzz, erase, slow, ect. Even adding plz to the end of asking for buffs if you want to be nice about it.
