Since there’s so many cool weapons and skills, it’s awesome to change the main playstyle on a character every now and then.
Especially when you have 1-3 main characters, and you named them before you had much experience in the game.
This leads to scenarios where your intelligence bow character is called Merlin, or a dexterity javelin+sword character is called Legolas.
It’d be handy that we can change a character’s name to better fit the playstyle we’re planning for the next x hours of play.
Note that this isn’t as prevalent in games where you choose a starting class and the options for that character are much more limited. But in Wicked you will be 100 hours deep into a character and you can think “let’s completely change this up”. I love that, but it can make the name pretty
