I guess it is dreadful for a "ogog generation"
But not everyone in this world is young and has "ADHD".
I know it wont happen and probably only a very very little minority would like this kind of gameplay but what's wrong with
a more relaxed gameplay where you have to think about overheal and if it is really needed to cast?
It won't be easier to keep the party alive this way! Two Cure too much or at the wrong time or for the wrong person and you've got a wipe incoming.
You have to think twice what you do!
I'm working all day I dont want to stress me with abusing keyboard/mouse/controller that's why I don't care about anything group relatet outside of story.
