I would like to see paths for:
Scout (wilderness mobility, superior tracking and especially stealth)
Archer
Melee (melee powers, but with a choice to focus on dual wield or not)
Beast Master (animal empathy/companions)
As a side note, I was a little disappointed to see rangers listed as "ranged strikers". Hopefully, by the time 5e rolls around, if they keep the focus on Rangers being ranged strikers then they will change their name to something more appropriate like "Archer". "Ranger" implies only a skilled and highly mobile expert at wilderness survival, and I would rather have had them drop the assumption of rangers as bow specialists. There are actually people out there now who think that the word "ranger" refers to ranged weapons!
