Ideally we'd want to change our names ingame. Currently it uses your steam nickname. Until the ideal feature is in, (where the game takes your steam name) why not make it just as many characters? Right now it seems WoR is three characters shorter than the steam name, meaning that people with longer surnames will find it difficult to cram everything, including company ID in their name without their surnames being cut off.
Found that out myself today where people kept calling me "Dew". XD
