“It’s probably Matt Mercer’s fault.”
It seems to me that smart play requires paying attention to the character sheet and so can't really be said to be mo0re important than it.
To clarify, I was using "character sheet" as shorthand for how optimized (or not) the character is. Meaning that a badly unoptimized character played well is (or can be) more effective than a highly optimized character played poorly.
