How do you deal with sluggish tanks?

There are sluggish tanks, and then there are tanks that refuse to accommodate for their DPS.

If you have strong multi-target DPS in your party, why are you pulling so little at a time when you can very easily tank two packs and have them die just as fast as one pack would? I'm generally pretty neutral on this subject, but this one thing annoys me to no end. When I'm playing a tank in leveling dungeons and I get a strong AoE DPS that is playing properly, I make sure to pull lots because it speed up the dungeon dramatically.

This is not a problem unique to FF. And it boils down fo this : it is not 'your' dungeon run any more than it is theirs. They can llay how they like. They are not pulling "too slow" unless they are missing some kind of timer and wiping the grp. They might be pullimg slower than you would like, but that is your problem, not theirs. This thread is full of extremes, used to bolster each persons argument. Slow suddenly means pausing for 3 minutes between packs. And quick suddenly means chain pulling speed run. Simple fact - if you are unhappy with the group, why do you have to suddenly start kicking players? Why cant you just be an adult and thank the grp, explain you hoped for a faster clear, and LEAVE THE GROUP. next time, to avoid this issue, you might like to tank yourself, or, more likely, form your own grp with intentions of a speed run.
