Nothing about the roles makes the Fighter not great at dishing out damage, and everything about the class makes them good at taking damage. Straight from the PHB.
True enough.
4e rangers don’t have to be one of those. …
The PH ranger was archer or TWF. The Marauder & (e)Scout were TWF, the Hunter and, well, (e)Hunter were Archers. That leaves the Beastmaster, which is fine for, well, Beastmaster(Dar?), but not so great for Conan.
It had perfectly good single attack powers, and eventually some minor action attacks IIRC. Not as much shield support as I’d have liked, but no class can do everything.
I can't pretend I ever took a deep dive into the Ranger class, it was a striker, the role doesn't much interest me.
I do recall a /few/ single-attack powers, but that'd be really limiting your selections.
And, for what? Some woodsiness? Slightly higher DPR than the Fighter?
It was pretty terrible, even ignoring how bad 3.5 feats are.
I take all kinds of exception to that.

The 3.x fighter design was downright elegant - can't say that about any other D&D class design. Extremely customizeable, and 3.5 fighter-bonus feats weren't bad - not whacktastic crazy-broken like everything having anything to do with Tier 1 casters, but /good/.
Sounds like a class that is versatile and gets decent skills. So, almost anything but fighter.
More than one class, was the point. You can't wring much versatility from a class system unless you start mixing classes.
3.x Conan, Barbarian for initial concept, Fighter to snag Great Cleave early, Scout or Rogue (and/or those first 3 levels of non-casting Ranger) for skills through his time with Red Sonja, back to fighter, or likely a PrC, in Aquilonia.
