Shelltron and critical attacks.

PLD doesnt need that, it is enough that he is already one of the best OT in the game.
You cant have everything, change sheltron and we will have to nerf intervention.

PLD best OT? Have you missed ShB?

TBN/HoS/NF all > baseline Intervention, and Cover nerfed useless as mitigation tool outside of cheese tactics.
To buff Intervention, PLD has to use Rampart or Sentinel, and then it's better to just voke and use Sheltron instead.
It has better efficiency for double tankbusters, but there are just a few of them anyway, and even then NF and TBN are probably better.
(WAR burst can heal ~20-25% of OT HP pool + 10% mitigation while healing themselves by ~40-50%, TBN is flat 25% eHP gain.)

PLD is nowhere near 'best OT' since ShB, but closer 'best raid wide mitigation tank'.
