Also, I've been thinking, Rangers get the spell Sleep as a level 2 spell. They get Level 2 spells at either Ranger level 8, or 10 depending on wisdom. Since everything with more than 4 HD is immune to this spells, it doesnt make a whole lot of sense.
Maybe it could be swapped for Ironguts? Not a powerfull spell, but could be usefull sometimes, and makes more sense for hardy rangers than sleep anyway.
