So, looking back on the thread, there's plenty of the same thrown around.

1) "SCH is uninteresting/boring."

Reflects in the trailer. Didn't really wow people, but drew their ire that nothing fun or interesting happened.

2) "SCH needs more than one DPS button."

Healer design. This I can see happening when they go to do damage control after SCH is kicked to the curb, if they bother. If anything I'll just be blunt and figure 'potency adjustments' are enough from how the combat team handles this job.

That's at least the two most common things I hear here anyhow(which are commonplace on the healer forums too). As for the White Knight list, I follow Deceptus on those lines because the veterans have seen more than enough over the years to understand SE and their handling of Healers in general - and their tendency to bring a lackluster response, such as taking a hammer to glass in the case of Warrior back in Stormblood for example when Shake it Off was just a self-Esuna.

The only things I can see for SCH are really if they actually do a big fairy rework somewhere mid-expac, honestly. And of course, if SGE was buffed somewhere along the line before then because of lackluster potencies, you're going to get meta complainers as well once things are solidified in 6 months after launch.
