Pld was not used because of the speedrun elements in everything. In terms of hate generation and negating dmg pld was better in most events in a skilled players hands.
For most boss fights I see pld as being superior tank when you remove the requirement of finishing the dungeons in 17/25mins.
War is better for non-bosses when killing multiple things comes into play. But it trades def for the dmg. Makes the fight more risky if something goes abnormally. Ask your whms you is easier to keep alive if you have any doubts.
