When we don't, that's when DD's complain.Don't get me wrong... you will get the usual Regen and Stoneskin... but stop acting recklessly and dodge that shite like a solid unit!
I know when I'm to dodging properly or not taking hate. But I'm also very highly aware of when I'm not being topped off and I have to switch out of damage skills to self-sustain skills.
And I'll be frank, some players are just not cut out to play the roles they play. That goes both for damage dealers and healers. But goddamned if healers are the more important to get that down.
This is why I love playing Jack of All Trades jobs as it allows me to prioritize assisting where players are having difficulties. FFXIV lacks that sort of thing right now, except for Bards. I like being able to shift tactics like that quickly. But it's not conducive to an MMO environment.
But from my days as healer/support. Triage of your DDs is a bad mentality to have, as it will extend your run time and provide even more chances for things to go wrong. Your healing priorities should be synonymous with the hate order, and healers need to do their best to stay as low as they possibly can go on that order - lower than the DD's as they're your tanks if the main tank falls for any reason - (Granted FFXIV makes that difficult with little hate dumping abilities.) and you can't heal or raise if you're the one having to kite or defend yourself.
So when it comes to restorative control, tank is first priority for all healing, then your spare defensive and HoT skills should go on the individual that's next on the hate list (Or if it's swapping between the two, the one most likely to take more damage.) Then on the line down.
Ideally, you should be taking the least amount of damage, so the occasional HoT on yourself should allow you to maintain. Only time you top yourself off is when you know you're about to get smacked hard. The only one lower than you on the priority list to immediately heal unless you're top on the hate list is Bards, as they should be smack bottom on the hate list and restore the self.
The priorities of Tank > Healer > DD has never worked for me. That situation assumes everyone is all taking the exact same damage and you're cutting off your 'expendables'. Your MP is equally irrelevant if you're fleeing from your life as it is if your dead or spent out. Your priority is the hate list, recovering damage on the top person of the hate list, and preparing the secondary on the hate list a buffer against damage when they take it. Everything else is HoT aside from emergency cures, which usually should be responded to by an AoE recovery/protection of some sort. (In this game it would probably preceded by Shroud of Saints, which is WHM's only real hate manipulation tool.)
Healing priorities should be a lot easier to maintain once 2.0 comes out and people will get a clearer picture on how hate is being distributed, so I don't think the complaints will last much longer past that. But keep in mind, Triage is bad mmkay? It's the absolute last thing you should think of doing.
