As of now most of pld quirks are fine. GCD stance dancing doesnt bother me i just weave ogcds in between and use them as cooldowns anyways. My adjustsments would be as follows.

Spirit Within- Needs to have a new passive to replace lack of silence. Maybe tie it to the oath gauge and move the cooldown to 15sec. 50 Oath gauge seems about right for it.

Devine Veil- Tie it to the Oath gauge. 50 Oath gauge to activate it. no CD. This effectively makes it a very handy CD. Also while up on the PLD gives a passive Regen.

Sheltron/Intervention- Reduce oath gauge cost to 25. This would allow more oath play for the skill and works well if devine veil and spirits are added in tot eh gauges costs.

Passage of Arms- Extend the buff for party members behind the PLD, as of now its only 5yalms. Most people dont realize it bu the wings tips extend to 15 yalms, half the time they arent even getting arms up passive and its annoying. Also shorten the animation time, you lose a full 2 sec of it with activation alone.

Shield Oath- Passive increase to block rate by 25%. It is shield oath after all. Also when shield swipe is used under shield oath you should gain 20 oath gauge.

Sword Oath- each auto should generate oath gauge, This would effectively give 10 Oath per auto. As of now Sword oath is really a permant dot for the PLD. I wouldnt mind a 5% dmg increase to all sword skills or something to make it more pleasing to the eye.

Sword/Shield Oath Release- This is a doozy. My Idea is to have both up and active at the same time negating the dmg penalty to Shield. The down side is it will drain oath gauge (about 10pnts every 3 sec) and you cannot generate oath gauge while both are active. This would be the crazy complicated play that pld would need to make them interesting.

PLD's are way to damn good this tier. Along with Whm they pretty much stepped on SCH/WAR/ASTROS from 3.0. They dominate the fights they are in with utility and dps but are simple to play. Ive mained pld since 2.0 and this is how I loved to play the class. heres hoping the dev team may consider my ideas.
