The tank is there to keep the monsters focused on them and, when applicable, to keep any direction AOE's they may have pointed away from the rest of the party.
The healer's primary function is to turn their MP into the tank's HP. There's also buffs/revives/throwing in Stone/Aero and such when applicable.
The DPS's primary function is beating down the monsters before the Healer runs out of MP which would lead to the Tank running out of HP which would lead to everyone running out of HP.
The problem is, the Healer's role is represented by people simply not dying and little health meters/buff icons. The DPS is just how fast the monster goes down. But the most easily recognizable and visual thing on the screen is "Who is the monster attacking?" Which is more or less in the Tank's jurisdiction. Everyone's role is equally important, but unfortunately the Tank's actions and mistakes are the most easily scrutinized.
