Good point! I didn't intend to downplay the importance of them, and I can definitely see how superfluous could be read that way. Cheers!
Did I misunderstand? Can you read the word superfluous in more than one way? English is not my native language.
It's not inherently a negative word, I don't think so, at least. You're completely right that keeping the game feel alive in itself IS a reason for them to be there!
