Hm, intereting points.
4th ed, currently, you cannot really do the "light/fast/int/dex fighter", so the ranger is that role, as it were.
So, maybe we need a "scout" class and a "swashbuckler" instead?
Or maybe those two, plus a dual wielder who uses heavier blades, if "swashbuckler" seems too much of a certain genre, ie, rapiers only, rather than ANY two weapon, light armour style.
I do not like the "skirmish" ability, in either 4th or 3rd ed, because, if you are
moving, you are not as accurate...it flies in the face of common sense, doesn't it?, lol.
But I don't see how else to encourage the idea of fast, light,
avoiding close combat style of fighting, without making it a boring
"I sit here and shoot you full of holes" fighter, either.
*scratches head, puzzled on that issue*
