100% support this. PLD and DRK would benefit the most from it since both use Spell GCDs (PLD has problems hitting a perfect 60s rotation due to spells being 2.50s and DRK cant use 5x Unleash / Stalwart Soul under Blood Weapon without it falling off after 4th).

RDM in fact doesn't bother with this since the only attacks that would be affected are all the unenchanted attacks and Enchanted Redoublement since 1.50s is the GCD speed limit (most enchanted skills) and Enchanted Redoublement is 2.20s.
