A game I'm playing actually has this logic lmao. You make 1 character when you start playing and you can level him up like hell and when you make the 2nd character (there's 4 or more slots) some of first character's stats will transfer.
So if you're originally lvl 70 and your stats are 6000 AP (attack power) your other chara would have like 4000 AP even as lvl 1.
That way you can PvP fight a lvl 30 person who only just started playing and has one character who's AP is 1000 with your 2nd lvl 5 character with 4000 AP lmao

Imagine playing an mmo and you're like lvl 70 or sth and PvP a lvl 5 and you lose somehow. That must be weird af for the actual players lmao.
