Why have the raid if there is no interest in doing it?

[CookieMonsta]

There is a vested interest in raid groups to "skip phases", correct? And this interest is very strong. It's so strong that if certain jobs do not facilitate skipping phases, they would be shunned. "Why should I invite X job when Z can do it better?" This quote should be familiar to Dragoon and Summoner mains during 2.4.

PLD can do all kinds of things that the other tanks would struggle with. For example, IIRC it remains the only tank that can do all 3 Quarantines in a row in A4S, can single-handedly deal with 2 fat adds in A3S (Silence+Stun) and absorb damage in A2S like nobody's business. The DPS check in Alex Savage was brutal on PLD but the bigger problem was the fact the fight had so much magical damage that DRK was overwhelmingly favored. If it had just a bit more physical DMG (e.g. if perpetual was Physical) DRK won't be so desirable even though they technically do more damage.

Also the essence of a raid is problem solving.
You take a really really hard problem, you formulate a solution, you execute the solution, you revise effectiveness of solution.
