Ranger: dual wield 1HS or use 2HS?

[Zuranthium]

You should be using a high delay 2H and swapping to a high damage offhand inbetween primary swings if you're willing to put the effort in.

Argent Protector 2H with Green Jade Axe offhand is cheap and a huge upgrade over your current setup. Argent Protector on its own will be better than the 1-handers you're using.
