Just a quick thought after reading this thread.
If SE were to:
1) Double the amount of hate PLD could accumulate over other jobs
2) Double the rate at which all jobs other than PLD's hate degrades
3) Give PLD a new form of provoke they could use at initial time of pull which cap's their hate on each new mob
Then, PLD would tank more often.
All that said, sure PLD would then be able to "tank" but they still would not have the damage output of any half decent DD tho I don't know that most anyone would care, as long as the WHM wouldn't have to work harder....but the bottom line is the mob is going to die just as fast with/without the PLD there.....currently.
As new content is added, and new HNM style nm's are made, I could see this having more value in the post-abyssea world.
>.> Editing the 1st post simply to add emphasis to the fact the original idea was flawed if the PLD had this much hate on them 100% of the time lol. >.<
