That's not really been the problem I've run into so much; in fact, it's kind of the opposite problem I've been having - people who clearly have a keyboard yelling at people rather than simply saying what they may have an issue with. Last night Force and I were doing Cutter's Cry for the first time, and one of the bosses spawns a million adds who go after the healer. I put them to sleep, and the healer told me I was "f***ing wrong" for thinking that was a good thing to do despite no one having told me not to do that and then proceeded to yell at me and told me if I casted sleep one more time he'd ignore any injuries the party took. Just tell me it's not a good strategy, and I won't do it, don't freak out at me because I don't automatically know what to do. Of course, it was the healer who kept dying first after that, and then the healer who threw a temper tantrum and said they weren't going to come back to the boss room and was instead going to "sit here and waste 27 minutes of your time" (the amount of time we had left in the dungeon). I wasn't being irate back, I hate being yelled at for something I just don't know, and the only time I even remotely snapped back was when he again yelled at me for not stacking. I didn't know what that meant, I thought he meant stacking my spells as that increases the damage, which I had been doing so I snapped that I had been, and then he basically called me a moron because that's not what he meant by stacking - which I just didn't know, again. I'm completely new to MMOs and as such I'm unfortunately not familiar with all of their terms. Stacking is in my spell description which is why I thought that's what he meant. But anyway, it's people like that whom I've been running into in dungeons lately and it really sours the entire experience. The dungeons are one of my favorite parts of this game because I love working together, but if I'm being berated, it really takes away from it.
