I don't think it's completely different. You are either performing the task for the party or you are not. That you do or do not receive a response from the member in question, or that you may run into conflict with one member in attempting to benefit everyone else, doesn't change that. Their performance changes only what can at best be expected your given party, not whether or not you are allowed to perform to that estimate as a party.

If the majority of the party wants to go out of their way to slow the run, then perhaps one should just do that or leave and queue again later. But if the majority wants to run at a unfettered pace and that pace is possible except for the ego of the tank, then I would situationally encourage the party to pressure that end, even if it means going past the tank and pulling for them. "Tank, we're doing full pulls. Use your Sprint just before combat to double its duration, get in one AoE of threat on everything and then gather the further groups. Open with HG/LD/SB and trickle CDs from there and we'll deal with it."
