It would be less of a dps loss for some people because you can then weave Suiton while still keeping up your GCD rotation. For someone like me, who's latency makes it so that it takes anywhere between 3-5 seconds to cast a 3-step mudra (clipping onto 1.5-2.5 GCDs), being able to weave GCDs/oGCDs would be a boon.

I don't think Suiton is supposed to clip our GCDs either. Technically it should only be a 1.5s (perfect, would like to say impossible) to 2s (expected) mudra as the cooldown between each hand sign is 0.5s, and most NINs I know are sitting on around 2 seconds CD for their GCD.
