The wider audience isn't a factor as I'm not advocating for the removal of the new system. I want an optional toggle to go back to the old system. There are no wider audience concerns here, this would be a win for everyone.
There actually is wider audience to concider ...
One group are people who want old system ... Another group are people who want new system ... And third group (probably bigest one, since it contains many people from both previous groups) are people who want both.
So i would totally appeal on wider audience! Its just that its argument in your favour, rather than against it.
The wider audience doesn't even know what we're are talking about, but they definitely won't want their human wizard being gimped from the start.
Imagine if Asmongold realizes he can't get 17 str on his human fighter. Imagine Asmongold's chat. That's the wider audience. Punishing casuals for playing they way they want is always a bad idea.
Elden ring botw there's a reason these games are so huge. Casuals can drop in and play however they want.
