The key issue here is you mentioned it's a level 63 dungeon. Levelling dungeons are often excluded from the general rule of tank stance use, and are often encouraged to use tank stance as much as possible since you cannot reasonable expect people to be overgeared for it. And in some cases the ilvl sync just messes with you more than you'd think.

Yes there are a lot of bad tanks out there, they take advice at face value, such as "Don't use your tank stance to kill things faster" without actually thinking about why.
The only way we can help is with posts like these, encouragement ingame, and maybe a few wipes to get the point across.
At the end of the day it boils down to this: tanks are not the only people in the party. When they choose to do what they want it affects the rest of the group and often ruins the gaming experience for the rest of the group. My personal opinion is that one player shouldn't have the ability to affect other people's gameplay in such a manner. I often think of tanks as Divas. We've all asked that tank nicely to please stop dropping stance when things aren't going well. 99% of the time it is followed by some horrible comments usually something like do better healer. So my personal opinion will not change on the subject I do not think that one player should have the ability to ruin the experience for everyone else.
