Do you guys actually play PLD or are you just suggesting any dumb idea that comes to your head?

"Cover or Intervention were simply a secondary effect for Shelltron if cast on an ally."
"oath gauge spenders like Sheltron and Intervention should be one skill"
"Merge cover and intervention. Cover is just better than intervention"

Sheltron and Intervention are perfectly fine as is and the only good change to make to Cover would be to revert it back to SB days where it was just a normal cd with the bonus trait of also giving 20% DR

"Holy circle and Holy spirit combine so they function like Ast's gravity."

If both were merged they would have to lower the potency on it and thus the Requiescat rotation would end up being shafted and end up weaker, so they would have to make more adjustments somewhere else. There is no need to make such a change.

"well delete Shield bash is an Easy one"

Shield Bash still has its niche uses, specially when the dps is abysmal and you end up running out of cds in a dungeon pull. They could make it see more use by making it have increased potency at the cost of Oath Gauge, otherwise it's fine as is.

"Royal Authority becomes Atonement while PLD has Sword Oath buff."

Honestly, that's a rather minor issue, i don't really see the problem with Atonement being a separate skill. Compared to Heavensward we still have one less button than we used to have since Savage Blade is gone.
