While I have generally been against combo consolidation, I could possibly come around to it if that meant more robust and interesting new abilities. Conversely, if it simply led to a job like Dragoon losing losing six buttons and they slap on a new oGCD you press every 60s. It will feel hollow and dumbed down. At least it will, imo. That isn't to say pressing 1-2-3- is any harder or more complex. It isn't. That doesn't mean spamming a single button the vast majority of your time playing combat related content doesn't feel boring. Ask the myriad of healers complaining about it.

It simply boils down to what do they actually use that new hotbar real estate for.
