My redone ranger;
instead of 2-weapon/ ambi, they can choose rapid shot (without the prereq PB)
Instead of favored enemies as written, they get a +1 at 1,4,7,10 etc. each bonus is for a a race as usual, but doesn't raise on it's own, you can add further bonuses to the previous ones. (so, you can add them all to Dragon, or have +1 in a bunch of different types)
They should get mobility abilities, like moving through woods easier, and I'd like to see an ability that lets them sleep less, or be more aware while they sleep.
I think barbarian's would be better off with favored enemies, and rangers should get their move bonus and evasion.
