I am not seeing anyone here suggesting we remove/merge all of the cross role skills. Since they aren't cross role anymore and we all get all of them I see no reason they couldn't just merge most of those back into the classes. All of those abilities that either interrupt or slow an enemy, merge that status effect into an ability in the class. Some abilities like True North or Esuna might need to stay. I could see this freeing up at least 5 buttons on everyone's bars, maybe more.
