Always go into a rework with a modicum of caution. MCH has been mentioned a few times with good reason. While MCH is a vast improvement over it’s stormblood iteration. It’s far from perfect, and I would expect similar for summoner. People who have mained summoner for some time will very quickly see through the flash and find the flaws.

New players or players that never really played smn at a high level will likely latch on and defend the rework to the death especially if it is easier to pick up than any other iteration. Hopefully it is better than what happened to mch but only one way to really know. Wait for expac and give it a whirl.
