"There's 17 000 variations of the story" is maybe more accurate, as variations aren't necessarily large?
Fextralife is apparently the sort of person to be pleased he can minmax multiclass with infinite free resets at every level. He was legitimate happy about this. I don't expect the guy to be very precise
While I personally side with you in that the 17000 endings claim is inaccurate, I feel like this is an unfair remark against the guy just because he has a different opinion than you in another matter, him liking the idea of easy respecs has absolutely nothing to do with him providing precise information. Also, consider the field he works in, accessible respecs will make his job a lot easier.
