To anyone who suggested whips: no no no no no. Don't ever suggest it again :O
I think there is no problem if there was an offhand item that required wilderness survival or beast mastery. A charm, an idol, a twig, I don't care. But you should be able to hold something that requires the attribute you are focusing on.
For example, when I play a pure healer, you are forced to take divine favour or smiting prayers if you want to do damage. There is no damage dealing item for healing prayers, fast casting, strength, anything that doesn't have a weapon associated with it. Rangers should be no different.
However they should have an offhand item, just like a healer can have a healing ankh req. healing prayers, or a warrior with a shield req. strength or tactics. And naturally these can have mods that people are asking for. There is no such offhand item for rangers, because they are always presumed to be attacking. Like I said, a pure healer is forced to take divine favour usually for the weapon, just like a ranger is forced to take marksmanship.
But what if... as everyone is saying.. the ranger uses his beast as his weapon? Can't he hold something in his hand that helps him? He doesn't have to attack with it. Same for wilderness survival. If you are out in the wilderness, surviving, you can still have something in your hand to help you. And since every other class gets an offhand item for their non-attacking attribute, I think a ranger should too.
Btw, stop suggesting whips
