I'm still using a 2HS at 32 brother, the 1HS weapons are just too weak and I don't proc quads often enough to compensate yet

Rangers get two very good quest weapons you can have done by mid 30s in the Short Sword of Morin and Orc Impaler.

Yes to both: Bone-bladed claymore is a good enough weapon to get into the 30's with, but there are also better alternatives out there you may obtain before reaching that point. I consider the claymore level-appropriate for the late teens/early 20's and basically okay through the 20's. It's starting to get long in the tooth by the early 30's and it's more or less obsolescent by the mid/upper 30's.

You can bbc while you orc impaler btw. Orc impaler makes a great range slot when you din't want to use the resist stick.

Give it a few more levels then I'd say go on a great adventure and head to Everfrost and get yourself a gigantic zweihander by bow kiting Karg. It is a challenge but as a ranger you've already shown you are up for challenges!

Did it myself at lvl 16 (or 17?) and not only was it incredibly fun but very rewarding. Fantastic weapon and you'll feel like a champ. Take out Matar while you're there and hopefully you'll leave Everfrost wielding both the Zweihander and the cloak of the ice bear!
