Right, and it doesn't mean that it does.
So the reflexive apologist tack of "well it's successful, so this specific detail must have been the only right choice," doesn't fly, even though it gets launched constantly when the game is doing well (or even when it was doing very badly, but still better than all other RPGs).
I probably shouldn't always be rowing against such an overwhelming current. I should just head for shore and leave this hobby to those who deserve it, since I, clearly, as one not keeping the faith, do not.
Well, you are pushing "We should have a PHB 2 because that's what we did for the previous 2 editions." Yet you can't really explain why it's such a big deal.
There are several things I dislike about 5E, but a design decision on what to name books that is clearer for the majority of people is a strange hill to die on.
