Really, what struck me (and I'm only realizing this now, so please bear with me if other people have already made this observation) is that the 4th edition PHB1 seemed woefully incomplete as a player's handbook. No monks, barbarians, assassins, druids, bards, gnomes, half-orcs... you can get away with a basic or starter D&D game absent those things, but not the freaking Player's Handbook. And yes, I was aware even then that these things were promised shortly to follow in future PHBs, and that "everything was core in 4e". But here's the thing: that shouldn't ever have to be the case. It can't be. The fact will always remain, the Player's Handbook is a core rulebook that you need to play the game; the PHB2 is a splat that you really don't, no matter how the marketeers label the cover. It's the nature of the beast that the first player's handbook will have lots of essential rules in it, and any future add-ons simply won't.
