No, I'm more opposed to the excessive lashing out rather than disliking the fact that someone isn't doing what they should. If you want to kick someone for doing it, do that. There's no need to throw a total bitch fit about it.
No it isn't. If you don't accept the queue when it pops because it says 2/4 bosses down you'd have to leave the queue and get into it again and hope for better luck the next time. You'd be in the queue AT LEAST twice regardless. So no.
