Did you like or dislike saves and BAB increasing with level in 3E?
Increasing with level and increasing at a uniform pace at everything for everyone are two different things.
And if you dig deep enough you will find somewhere a post from me advocating that wizards, for example, should gain either NO progress or a much slower (1/3 or 1/5) progress in their BAB.
1/2 for wizards vs. 1/1 for fighters is acceptable to me.
1/3 vs. 1/1 would be an improvement.
1/2 across the board is not value added for anything I seek.
I think it's just an extension of that. Maybe you would prefer if Reflex Saves were also a skill.
I'm not opposed to it, but I see no need for it either.
I believe you could only create a reasonable system for having "skill points and skills for everything" if you also have a mechanic that defines how you gain skills by using them, or explicitely training them.
There are some systems that do a reasonable job of that. But I completely disagree that it is needed.
Any way you slice it, I've got a decade now of showing that the 3E skill system works more than well enough for what I want.
If you don't have all that...
1) For "believable" advancement, they need to track skills used on their own to argue that certain skills should be improved. (And if they didn't want "believable" advancement, why not go with the +1/2 levels anyway).
Because a system that doesn't get hung up on the strict justification for WHY a skill improved is a completely unrelated to the idea that everyone shouldn't progress at everything at one uniform pace.
You seem to be making up complaints I didn't make and attempting to refute those rather than addressing the point I did make.
2) Players have to manage a lot more minitua as they have to remember all skills they may find important. I often find this problematic in games with extensive skill lists, as you have to check manually whether there is a skill you may need to actually describe your character's vision and advancement correctly.
Again, in over 10 years of playing 3E I most certainly DO NOT find this infrequently problematic. Much less "often". Why are our experiences so sharply different?
3) Also, another risk is that with a too detailed skill list, you can't even create characters with "reasonable competence" in skills that you expect them to have. If your resources for improving skills are limited, you will at some point need to make choices were to invest.
In 4E, you can fare reasonable on an untrained skill since you have ability score mod + 1/2 levels. In 3E, you can have a 5 point difference by 2nd level, and it only grows from there. (And mind you, this is not about making the character that can do everything - but just a character that has a reasonable chance to do some of the stuff you associate with the concept, without being a master at it.)
I'd like to see some improvement in 3E in rounding out character skills. No doubt about that. And this point is a valid upside. However, it is a trivial relevance because sacrificing the quality of the system for important skills to slightly improve the system for secondary skills is far from being a win.
Climb is a perfect example for an adventuring skill. Of course you get better at that from adventuring, because you travel through the wilderness and through dungeons a lot and have to climb stuff occassionally!
You just contradicted the point you made before about why this system was more relevant to non-adventuring skills. That was what I was replying to when I pointed out climb here.
