PLD has way more damage mitigation and a lot more defensive cooldowns then war. PLDs have better utility a stun with no cooldown shield bash and a silence as well with spirits within. Silence is very important when fighting the ADS mobs in Coil.

Its just bad bringing a warrior to coil not only will they take more damage and be harder to heal, they won't be able to silence high voltage on any ADS type mob. Makes almost everything harder taking a warrior to anything SE needs to fix the class.
