I feel like PLD is a tad bit overpowered. I could see that back when we saw the damage potencies from media tour videos. But aside from the obvious damage complaints everyone has about evvery job in every game ever made. Real job changes to fix existing issues:

*Shellwark(Enhanced Shelltron) should be 5 seconds base and moved to level 35. Then at level 74 you unlock the enhanced version, giving you 10 seconds to line up with other buffs. Seriously I can't believe that Shelltron and Bulwark weren't combined 4 years ago they go together like peanut butter and jelly.
*Cover needs to have a "Rescue" treatment put on it. Its range is so small that when I try to save an ally they are always too far away. If they are going to nerf it back down to 0% mitigation, then for the love of christ, please auto-pull the party member to us so we can cover them like healer's "Rescue".
*Return Flash as an oGCD for a little bit of extra mitigation. PLD feels much squishier than the other tanks IMO.
*Maybe Divine Veil on Oath Gauge.

Otherwise PLD is the greatest it's ever been and I'm freaking ecstatic they continue to truly EXPAND upon PLD with every EXPANSION. Unlike DRK (Goes through three reworks and it still plays like a lost and confused child in the mall.)
