Eh, a new player starting with a Wretch will get their ass kicked by damn near anything tho. It's going to be somewhat demoralizing, IMO they're way better off starting with something newbie friendly (Samurai, Confessor, Warrior, Vagabond IMO) so that they can get some decent stats and gear to start with.
Wretch is more a class for seasoned players who want to fine-tune their early build than for noobs (or be that guy on Youtube who beats Malenia at level 1). And even then your starting class is made entirely redundant the moment you finish Raya Lucaria.
