Fighter 1, then Wizard 1 = 30 accuracy + 20 accuracy= 50 accuracy
Wizard 1, then Fighter 1 = 20 accuracy + 30 accuracy= 50 accuracy
It's equal!
But it's so unbalanced. They'll need to find some hack for this.
Personally i'd do
"base accuracy = average(class A lvl 1 acc, class B lvl 1 acc) + X * (character lvl -1)"
but i'm just a simple person who does not understand the superiority of 5 person party limit so what do i know ):
Level 1 stats have to be pretty deceptive though. How fast do you get past them? And depending on other choices the build makes as you steam by them might the character be a frontline battlemage wielding a sword casting spells upping his accuracy or a backline battlemage throwing down fire but wielding the sword better than he used to?
