From the post:
Rangers have a long tradition in heroic adventure. Whether they're portrayed as lone striders keeping the edges of the wilderness free of the threats that lurch forth from the world's shadows, as hunters tracking down fugitives or beasts, or as skilled archers serving as a scouting force for a local lord or group of village elders, rangers have a special place in our fantastical imagination.
For the Pathfinder Playtest, we decided to cleave closer to the core principles of the ranger—a rough and tumble warrior in the wild, possibly of the wild himself. Because of this, the most significant change we made to the class was that it no longer has spellcasting ability, at least as a default. Of course, this doesn't mean we have to abandon this aspect of the Pathfinder First Edition ranger forever. Because of the way classes are now structured, it would be easy to create a spellcasting build of the ranger later using Spell Points (like the paladin), but for the Playtest, we are trying out a a spell-less ranger.
But enough of what the ranger doesn't have. Let's take a look at what he does.
