Pretty much every tank thread on BG is in agreement PLD is a liability in A2S. Not unusable, but a liability, the shield simply isn't enough.

As for T4, Hallowed into sentinel for the double dread and to get hate before kiting on the adds at the same time was what made PLD so good, a shield was never what made the difference, even the shield CD bulwark required stacking with convalescence to survive the double and stacked dread phases.

The shield has been a balance issue for PLD for ages because despite the mitigation being easily calculable, it is often overprotected into being some permanent rampart when it is nowhere near.
