IMHO as a PLD, just be flexible,
1. your team is smart, they wont sit behind you. we become a happy tank...
2. your team is lazy, and sit behind you, we as a tank, move the boss away....
this is multiplayer and multipersonality character in 1 game, you cant expect to standardize the people, that can be 6 years old kid or 70 years old guy that have a super ego
