Expert Long Rester
I wish I had your self-discipline.
It's not just restraining myself though. With things like Advantage and the Lucky feat, I hardly miss having a maxed out score. What's the point of rolling a 24 when a 18 hits? I find having multiple dice to try and hit that target feels good enough that I don't miss the +3 from turning a 14 to a 20.
Edit: I have not done the probabilities to see if the above is mathematically worthwhile, I just play and try to see if I feel like I'm no longer being effective.
