My rule is simple: if I end up dying and my healer wasn't SPAMMING me with heals, that's honestly their freakin' fault. Like no, I get that they might want to do "other stuff" aside from healing, but when you're doing big pulls your NUMBER 1 PRIORITY should be to make sure the tank doesn't die. And if that means spamming heal after heal after heal and use cooldowns to get heals in faster and putting down defensive stuff, then so be it! Or we can just wipe and go back from the start. Idiots.

Like I'm tired of killing the second boss in Ala Mhigo and pulling those two packs just before the big swarm of dogs, and healers not being able to keep up. I pop ALL my cooldowns and STILL, some healers don't keep up! Is it really so hard?!

Also you mentioned Bardan's Mettle. At the START OF THE DUNGEON, man... very first thing, I pull the two packs. Half of the time I have to Holmgang before healers start to step up their freakin' game.

Now I've yet to do a pull big enough that it ended up being "too much", but I'd say if even with the healer spamming heals on you, you still died, then you might have ended up pulling more than you should.
