Entitled DPS, please stop being entitled

[Tuathaa]

Definition of entitlement: the feeling or belief that you deserve to be given something (such as special privileges). As you said that SE chose you to be tiebreaker as a tank.. well.. the definition.

SE did not choose the tank to be the tie breaker they choose a random player to be leader which is designated by the L next to their portrait in the player list. Ultimately it is the party leaders say and not some random dps, tank, or healer.

I think there is a huge difference between being a leader and a boss.

A leader is meant to LEAD, not to give orders or take final decisions.
So yeah, a Tank is the party leader, but not party boss.
Tank is just meant to lead, not to decide alone if runs will be 'full clear' or 'fast clear', or if group will deal with massive pulls or not. It's up to the group to decide things altogether (if you running with a premade party, you guys can decide who is going to be the boss).
Nothing in this game (raid, dgns) can be done without a specific party role. But be pretty sure: Anything can be done without YOU (yeah!! you there!!! Reading my post!!! lol).
