People still seem to be missing the "polite communication" aspect. Three complete assholes demanding you big pull don't deserve big pulls, especially if you can tell they're a 3/4 premade who didn't bring their own tank. If someone asks politely, and you're comfortable with it, no harm in changing your pace. If someone asks politely and you aren't, say as much. Even if the majority wants them, the tank's consent is always required for big pulls. Always. I'm honestly unsure why people seem unable to comprehend this.
