I am thinking of giving Rangers in my games Expertise, at the same level as Bard. I feel like it fits their area very well (Expert woodsman/wildman), and honestly would fix one of the biggest problems I have seen people have with them. The fact that Fighter can be a ranger just as well as a Ranger can. Having Expertise would give them a nice boost to Survival (If they choose that), making their only real competition in the area the Rogue and Bard, who both lack the Nature related options in-class that ranger has. Thoughts?
