I don't mind the change, I don't think it alters the roleplaying or flavour of the class significantly.
My son, up to EA BG3 completely ignorant of DnD, was absolutely baffled, bewildered and bemused by the character creation process.
In spite of all the tips and tutorials The Oaths - and other sub-class choices at Tavgenesis - were yet another complicated and confusing matter.
Hence IMO moving the choice of Oath to later would "lessen the pain" for newbies.
But I understand the point of "no oath" = "Fighters with fancy spells" before taking the Oath.
