Maybe I’m misunderstanding something? (And this is a genuine question, not trying to be sarcastic or judgmental or anything, I feel like you’re reading the situation differently than I am and if I’m reading something incorrectly then I want to be corrected.)
I don’t understand how a stat board wipe would allow for more flexibility? Like, in the first game you can do fine even if you don’t train your “main” stats, and I really liked that. But then just having set in stone new stats for each route after a game (potentially two) of developing your character’s strengths isn’t really a mechanic retcon, it’s a character skill reset, which–and maybe I’m wrong, I’m not the one coding or writing the game–feels like it wouldn’t really add flexibility, but unnecessary rigidity. Especially for the people who aren’t keeping up with these developments and won’t know exactly what class goes with what route (or RPers who don’t pick classes and routes based on stats so much as the character their developing) who might end up pushed into a character build they weren’t expecting or won’t enjoy. And if they’re attached to the stats they’ve built up themselves, there isn’t really a route that’s just “beef up everything about myself” (understandably, since that’s vague and uninteresting), they have to pick one of the three, that don’t spell out within the text that they’re coming with a stat reset or what that stat reset will be. It’s better than picking a new build blind, but not by all that much, and not clear that they’re going to end up picking a new build.
Again, I don’t think this would break the game or kill my enjoyment or anything, but I do think it just seems kind of frustrating and takes away some of the meaning of the character you’ve built up and worked on before the end of the route.
