Lowering the GCD is as close to anything on the never list. We will possibly do it for hunters, but that is because their resource system is going to prevent them from ever spamming multiple buttons at once (in the same way rogues have a lower GCD). Even with rage normalization there are going to be times when a warrior is at 100 rage and can unload with multiple attacks at once. The GCD is there for a reason, partially for game balance and partially to keep the server – client communication from getting gummed up.
That just makes sense. Our 1.5 second GCD that doesn’t get reduced by haste is currently a necessity, but once we’re more constrained by focus, then they can give us the same kind of GCDs other physical classes get.
