Disarming Traps is a skill that rangers would have, but not to the extent of a rogue would, as a ranger’s experience with traps is more limited in scope. A score of 65 to 75 tops would reflect this well. They do have an understanding of many types of traps like deadfalls, trip wires, snares, pits, just not as much as ye old rogue.
Picking locks is a skill that rangers would possess little to none of, perhaps a score of 20 to 25 max, if that, and then only because so many people are used to rangers having this skill.
On the subject of the rangers’ ability move stealthy. Unlike a thief, their skill is related to the outdoors, not cities and dungeons. To reflect this they should have fewer random encounters on the world map, and a reduced movement cost as opposed to other classes.
When it comes to melee, I have no complaints with the class; it is about where it should be. I do like the idea put forth that quivers should be containers that will hold the arrows of your choice. I also like the concept of crossbows doing more damage, and then they must be reloaded. Very realistic, and brings some strategy to missile weapons. Bow use should not be speeded up, it takes several tenths of a second to draw an arrow from its quiver, and several more to draw and release it. Only a few archers in the world have been proficient in this fast of a shot, even Howard Hill had his limits, people watch too many movies. But these last ones are not just ranger issues.
I will await more comment before I continue as I am suffering from sleep deprivation at the moment.
