@Starteck, I'm just going to post something to throw some different perspective in here; it's a personal experience and not the norm, but it's still something that did happen a few months back:

>Queue into MSQ roulette as DPS
>Got in: one new player (tank) with three buddies, one of whom is a tank and another is a healer
>Tank buddy demands we stop everything to accommodate the new player - refuses to pull, healer buddy tags along with them and refuses to heal us
>We try to go anyway, but the second healer was poorly geared being new themselves (not to the instance but still having the leaf), and there's only so much we could do, so we spent 20 minutes doing everything at the pace of NOT ACTUALLY MOVING... not even reaching the second boss in those 20 minutes (it was C. Meri btw)
>Someone inevitably snaps, insults get thrown back and forth, tank buddy jests and because, as you pointed out "we queued for a roulette and should have known new people can join, therefore we are obligated to go by their pace"
>Another someone snaps and leaves, I left second, no idea what happened next but i'd wagger everyone except the people in that premade left as well.

Now, keep in mind - most of us there having to wait were DPS jobs, and we got in after having to wait well over half an hour, only to be met with this kind of nonsense. That was a premade of FOUR PEOPLE - this happened in HW, they damn well could have just unsynced it with little issue. What did they choose to do? Queue normally to let someone enjoy the dungeon "as it was meat to be", resulting in nothing but wasted time for all people involved.

This, of course, is clearly not the same as what happened in your case - but what if you'd brought a third person with you? A tank or healer, perhaps? Then yes, you'd effectively be wasting everyone's time - only ONE of you was new, but instead of trying to find a third person to unsync with you you could choose to do as that team did, and all but hold the rest of team hostage unless they'd be willing to eat up the thirty minute penalty.

That one healer in your team, while rude AT THE END, still let you do the run slowly as you wished. Could have been nicer, could have been worse too. As could YOU have done something else. That PF argument you keep throwing around, it goes both ways.

It's not that I don't think new players don't have the right to watch cutscenes - honestly, I do. In most cases missing up to three people is barely noticeable... unless, as the healer said, the person(s) lagging behind are healers or tanks.

End note: It's an MMO :/ there's not a single game with social aspects to it that DOESN'T see this type of behavior at one point or another. That type of comment? A pinch of salt thrown at the end? Probably just a little venting, as you did here. People can have bad days, and the only thing that healer soured was the end of your run.
Sometimes people are just not in the mood to be accommodating.
