Re: A level of confusion
I'm glad you agree.
To me, ranged and HtH weapons/attacks are dissimilar enough that I can think of few situations that it would seem reasonable for a single skill level to apply to both. And in the situations that I did, I have no problems with using limited 10 point levels instead of 5 point levels.
Of note, just because things can be put into logical groups does not of necessity mean that those groupings are also functional ones. You could divide bladed weapons into those with wire wrapped hilts and those without. Perfectly reasonable groupings. However I wouldn't say that it would be reasonable to buy a single skill level that would apply to bladed weapons with wire wrapped hilts, but not to ones that didn't.
I prefer to look at all CSLs as being based on the 10 point level, and the 2, 3 5, and 8 point varieties just commonly used "pre-built" limited versions. Most uses for CSLs will fall into one of those categories. For ones that don't you just build your own.
