My opinion of the 1 button idea is that it initially feels good but ultimately ends up hollow

It feels good to get to the point where you understand why oGCD’s are so powerful and you can juggle your oGCD’s with your damage spells and you start having 100% uptime on fights, you feel powerful and you feel skilled

But then after being at that point for a little bit you kinda realise that that is sort of it for healers, there is nowhere to go from there and that’s really when it starts to feel hollow
