Why expect them to dodge but not expect them to use cooldowns to prevent damage from unavoidable damage? Dodging is done so they take less damage, just like using Manawall or Manaward.
The purpose of a DPS reducing their damage taken (whether through dodging or using cooldowns) is so the healer can focus their resources on keeping the tank alive. A dps who refuses to do this is hindering the entire party by being a bigger drain on the healer's resources than they need to be. And while there's a good amount of content where dps can pretty much let -everything- hit them unmitigated and the healer can keep up and not run out of mana, there's plenty of content out there where this isn't even close to possible, and I'd rather teach them this (even if it requires making it a "hard-learned lesson" through them dying repeatedly) in the weaker content than let them go through to the harder content and fuck things up for everyone.
I don't yell at anyone. Nor do I refuse to heal someone who simply made a mistake and took more damage than they should have. It's people like you who intentionally refuse to use all the tools at their disposal. A black mage who refuses to use Manawall and Manaward is no different than one who refuses to dodge abilities. They're intentionally being a larger drain on my resources, so I will quite happily let that person die and keep the important people (like the tank) alive instead.Sure I suppose it's nice if a BLM would mitigate damage when applicable from a healer's perspective, but not every class has access to cooldowns like that and I really don't find it necessary. I just heal. If a BLM took a hit, because Manawall wasn't up, I don't yell at them and insist they use cooldowns, nor do I blame defeat on such a thing. I. Heal. Them.
And to clarify, the healer's primary job is "Keep the tank alive." Keeping other party members alive is secondary, because without the tank, you're probably not going to win the fight. The other party members staying alive, in most fights, is largely their own responsibility, through dodging and using their own cooldowns (ranging from damage mitigation abilities to ways of restoring their own health with things like Second Wind), with the healer augmenting that as they can to help deal with unavoidable damage.
As for DPSing, defensive cooldowns actually assist in DPSing. You've already been told how Aetherial Manipulation can improve your DPS by letting you stay in place casting spells longer. The same is true for Manawall and Manaward, as they let you negate damage so that you don't necessarily have to actually dodge everything, or give you a needed buffer so you can safely Convert (example: manaward + convert during enrage method of Turn 2 so you don't have to forego that part of your rotation, or manaward + convert if your rotation happens to put that part during stomps from Titan). I haven't actually tried it yet (so I can't confirm this example works) as playing a lot of other classes has in-grained in my head "dodge Landslide always," but I've been told that Manawall will actually negate the knockback of Landslide in addition to the damage, meaning whenever Manawall's available, you can just keep nuking Titan instead of stopping to move out of the way of Landslide.
So yeah, you can either continue with your narrow, incompetent thinking, or you can actually realize how wrong you are and improve and maybe become actually competent.
oh, and
I'm not even the only one who's been repeatedly telling you the value of manawall and manaward and not to macro them together, but keep being oblivious if you want to remain incompetent.only with you
One more note: "I don't expect dps to use defensive cooldowns." That's a very lackadaisical attitude.
