How would they fix PLD 4.0?

[Reynhart]

I like your pld idea but I don't know if it necessarily needs that extra defense

PLD surely don't need the extra defense. But since the meta tends to favor using tank stance as little as possible, it would give an interesting synergy that a PLD OT will allow for even less tank stance time for the MT. If the MT can stay out of tank stance more, he can maintain a highest DPS, to compensate for the native lower DPS of PLD.

Granted, it's similar to a warrior's stance stacks

WAR is not the only job that build a ressource by its rotation, so it's always an option. However, if it's tied to blocking or taking damage, it still cement PLD as a "MT job", which is part of its issue, whereas transfering buffs (Defensive and Offensive) or having a barrier-heal can be useful on MT and OT.

Another reason behind the Galvanize effect is the concern of the role-skills. We can assume that the cross-class skills will disappear entirely, so PLD might lose Stoneskin with this. By reworking Clemency, it would serve as a stoneskin replacement while making it much more useful.

And, on a last note, I'd also slightly change Divine Veil so that the barrier actually scale with the healing received to trigger it. Like 30% of the HP recovered. It would still be a burden to receive a spell to activate, but it would reward good communication between the PLD and the healers to save a powerful spell for that, opening new strategic use for Convalescence...as an OT.
