I’m sorry, but I fail to see how “it used to be worse” is a valid arguement in support of this change being what’s best. You are, of course, entitled to your opinions; but I disagree with the way it’s being argued.
Personally, I still think that either the repair % per hot OR the flint usage should be scaled back. I would even be fine with the repair % being set back to the way it was and flint usage increased to make up for it. The cost to maintain a base, I understand. The extra time spent doing so is more of a pain, in my opinion.
