Lower GCD?

[Rongway]

Really feel like we could benefit if GCD was lowered by a smidge, ideally half, and I extend this to the other roles as well, especially healing.

Have you ever tried to use both Displacement and Fleche in the same GCD? It can't be done without delaying your next spell. If the GCD were halved, we wouldn't be able to use even a single oGCD without delaying the next spell.
