I think the switch to acending AC probably qualifies here. It's undoubtedly simpler to operate and it doesn't sacrifice any granularity of mechanical outcomes.Can you please give me an example where more simplicity doesn't lead to fewer mechanical outcomes and/or less granularity?
And please provide evidence that simplicity in and of itself is a reasonable goal, but complexity never is. Also, your "sweet spot" is obviously another way of saying it's subjective, so the simplicity is always better principle still doesn't apply.
I don't say that it is 100% better, I get that there's a certain nostalgia to low AC = better, and also it communicates something about the scale of different ACs that 'high numbers are better' doesn't. But overall I think it's clearly better.
