Well
The first ranger of the Strat Rev 1 vol2 was a survivor. He had high stats, a bonus HD, was the only one who could track. and dealt bonus damage equal to his level to most nondemonic humaninod enemies (back in the days when enemies had low HP). And you could barely surprise him.
No spells or animals until level 8. He didn't need them.
Before level 8, the old school ranger massacred enemies. He'd sneak up on the foe, surprise them, and carve them a new breathing hole 4th-edition-style.
But after level 8, the monsters start cheating. Spells and deadly eye rays and fire breath. So the ranger metagamed and got magic. ESP, healing, and animal scouts.
The ranger is the metagamer of warriors. And if D&D Next is going to have tons of cheating monsters with their magic, breath weapons, eye rays, poison, invisibility, scrying, and fogs, the ranger needs countermeasures.
