If they make the controls more complicated and go back to heavensward there would be a mass exodus of players from the game. The current content balance has had better player retention then Stormblood, but I do feel like due to how they have to do difficulty in this game people are either having an engaging time the first few times they do something and then it gets boring, or it turns into cram school for hours getting frustrated at that one guy who didn't do a mechanic right because he is still learning something earlier in the fight than the rest of the group. I mean getting into the higher tier content feels like someone is applying for a job and often times that application needs to be made months in advance to even get in.
