PLD is fine as it is.
Vail is never a problem to prog and a pld or any Tank don't need shields for raidwides.
20 sec CD is not a problem.
During prog you just skip the first FoF and start to do the full CD when the Kill is close.
Other classes need also a countdown.
Besides that, i hate insta pull tank's.
A at least 5 sec countdown should be the norm for all bosses.
Defensives Is also not a problem because in exchange of that you have a additional 15% group mitigation.

The thing that really needs a fix for PLD is it's level 70.
It is just not fun and basically unplayable in older Ultimates.
Like, i first timed GNB in Ucob and did 500 dps more then with my PLD.
