This one's kind of shaken me tbh. I know the best trait any healer in this game can have is thick skin, and I usually do have that, and I also know that none of this was my fault.
But, I'm really a bit annoyed / shaken up by this entire thing and truthfully it's put me off doing ST for a while.

Setup is 1 pld, 1 blm, 3 smn, 1 drg, 2 whm.

ST, Scylla.

DPS don't dodge anything, don't move to the electricity platforms when tagged with the thunder orb and don't match fire with ice orbs. Other healer also gets KO'ed twice - and it's a big effort for me to manage. I'm resorting to medica'ing, regening people frozen, and using other parties' puddles because we have none. By the middle of the fight, I've raised 3 people and I'm getting low on MP. Dragoon dies, again. Scylla uses her big attack, so I swiftcast raise the dragoon and head for the platform to medica II everyone and hopefully regain some MP. Surprise! We're all petrified. The dragoon then accepts raise, pops up with us, swings round the oceanus to face us, engages it, and we're smacked with it's conal and all die because we're relying on my medica II to recover HP slowly.

Every single DPS complains at me at this point, telling me to heal them. I say to them that I had to raise 4 times in that fight because no-one wanted to do orbs / puddles, and obviously can't heal while petrified. No-one can heal while petrified, what do they all expect?

SMNs tell me they'll grab raises from then on, DRG is still bitchy about it. I say ok, we clear.

2nd boss.

clear first time. PLD is new, makes the mistake of grabbing another party's giant after ours is already in place, tanks other pt's giant with our giant. Alliance starts complaining, SMNs don't grab raises at all and I call them out on it. other WHM dies repeatedly again. (I really don't know what he's even doing) 2 smns argue the fact they shouldn't have to raise and then leave, replaced.

3rd boss.

DPS aren't taking down slimes, I get complained at for being in cleric stance and stone II'ing slimes. I tell the DPS to do their jobs and grab the damn slimes, and that I'm switching out cleric stance accordingly before healing, what's their problem? Other healer dies again, thanks to 2 DPS being tagged with bombs and running right into him. Together. I raise the healer and get frozen. Then we're told in /a from another healer in another party to step up healing. The other WHM blows up, saying I was frozen and he was dead, what does he want us to do?

Fourth boss cleared with no issue.

Believe me, I've done ST a lot and I'm always walking away with at least 3 commendations. I know the fights, I know what I'm doing, and I know in this instance I was not at fault and I simply cannot heal through people paying absolutely no attention to mechanics and the other healer being dead / brink of death with about 200 mp on them. What is it with DPS? Why is it a case of people bitch/whine/complain at the healer immediately, without even checking if there's any icons by the healer's name showing that they can't do a damn thing?
