tbf there are arguments that can be made for FE but comparing it with Pokemon, where every newcomer sans Pichu is looks and plays completely, differently really isn't it, even if I wouldn't care if they stopped adding new mon altogether
it's a shame that Byleth is the one to reignite this debate about reps though, as they do play distinctively and address the longheld complaint about FE weaponry
also while I agree that 'x series shouldn't have more reps that y series' can get a lil tired, as they fixate too much on arbitrary numbers (I want another Zelda character but not like Toy Link or some **** just for the sake of it), being a fan of a series and getting tired of never seeing it get a new character is not an invalid sentiment
