Tank is supposed to be the first to enter but also the last to leave the battle. Like I said, this is the definition of the warrior in FF11's manual. And it's true. Only tanks know perfectly what does that mean and most importantly what does that imply : if something goes wrong, we are supposed to take the blame since we give the pace of the run. Mobs are not supposed to go after others since it's our job to make sure it never happens. Thats the only way for everyone to enjoy the game at its fullest. Most of players will definately feel reassured when they have a good healer but also a tank who doesnt hesitate but also when the tank knows to avoid risks when it is necessary. And not act as a dictator. But that's also a reason for the other to respect the tank's job too... It's symbiosis and harmony to show some respect...
