My argument was more "since stat allocation does exist, there are still things you can use it for" since the person I replied to said it didn't matter anymore. It's generally an unnecessary system and how they handled SMN/SCH was a bit of a mess for anyone who wanted to play both (especially when Hymns weren't cheap). With how linear stat progression is the materia system is largely a waste as well. Both the stat allocation system and materia are simply an illusion of choice in the most fundamental sense, they could easily remove them and just give everyone base generic stats that did +HP, +damage, and +healing. It'd change basically nothing.

Anyway, that's another topic entirely. Basically they could do away with the system, sure, but while it's around it still has uses. Still does something, even if it's not that big of a deal.
