WAR would need a rework to its kit for skill speed to work in a flow stand point. This is NOT to say I disagree with WAR moving forward pivoting towards a SKS tank that hits hard when it goes through a solid ramp up.
Each Tank has a sub theme to them with GNB being a OGCD weaver style giving it a feel of being fast paced but not being overly fast in GCD stand point.
DRK is built completely on always using an OGCD while PLD has an identity of ranged supremecy.
WAR doesn't have an identity outside of DH/CRIT but that has been problematic to rely on since its inception. Its either way too strong, or way too weak. I don't think completely ruining the DH/CRIT would need to be removed, but toned down as a reward for the skill speed of WAR as a pinnacle pay off ( a requirement to EARN Inner Release so to speak).
From personal preference I really enjoyed WAR back in SB when my AST feed me arrows as no one in my static ever wanted the darn things except maybe my BRD.
