Barbarian? I hate it. Perhaps if they had called it 'Totem Warrior' or something similar then it would have made a little more sense as the lightning, cold, thunder and fire powers appear around it. I would have greatly preferred a more 'classic' barbarian. You clearly couldn't model Conan on this class!
Character Options
Backgrounds - I was hoping this would be good and it was feeble. Basically it gives +2 to a skill or an extra language associated with an aspect of a 'background'.
I was hoping that this would be at least as good as the "Forgotten Realms" background or the "Scales of war" background; perhaps even something for rolling up a nice detailed background for characters as we used to have fun doing in the 80's. it seems that no design work or crunch went into this at all.
Just curious... what were you expecting it to be? What should there have been in addition? Take out the combat chapter, and you just described the PHB Uno.
I would have liked to have seen a Combat chapter which included some additional combat options (naval combat? aerial combat? mass combat?). If the PHB is the book which contains combat information, I expected each PHB to have something about combat, especially since there are loads of bases which haven't been touched yet.
Given that rules for mounted, flying, and underwater combat are presented (albeit briefly) in the DMG, I'd expect rules such as these to appear (if/when they appear) in future DMGs, not PHBs.
every class has both been lauded and dumped on, which means they are probably all done very well indeed.
