While I agree with you and understand your frustration, I was pretty sure just about everyone here is on your side of the fence. We want a better skill description system as bad as you do, and I've said that it's thanks to you and your actual fresh view of Althanas as a new member that helped jumpstart this whole movement to improve the forums, and to make it easier for new members to integrate into the IC and OOC community. My first post even stated that I don't wonder why people leave: it states black-on-white why I think they do and why these guidelines are being written in the first place.
I'm not sure if you've missed it, but these guidelines, if accepted, will allow you to re-register Vestagar exactly as you intended, with the mastery of all the core skills you wanted, if not more. The only thing we're not yet agreeing on (and not out of stubbornness, just out of trying to see everyone's point of view) is what descriptor system to use for skill levels.
The only reason I used the average/above-average system in the examples is because we haven't decided on what to change it for, yet. As you can see, these example characters have mastery of skills related to their concepts, and everyone has, to this point at least, agreed that they are adequate for level 0 profiles (outside of a few kinks). Once we decide on a system, though, I'll edit the examples to better reflect how the skills work.
This whole thing is to stop the shoe-horning you mentioned, so I'm a bit at a loss why you're mentioning this. If this does go through and we all agree on a function skill descriptor system, I don't think there'd be any problem left unsolved among those you listed. If there are, however, I am very sorry for being unaware of them, and would be glad to edit the guidelines to deal with them too.
Edit: Also, I'd be really happy if other people would contribute with Character Examples that I could edit into that post. If anyone wants to test out a battle-oriented character, I invite you to do so.
Edit #2: I added a pure combat character example. Express your agreements/disagreements with it freely! Also added a "Guidelines for Familiars and NPCs" section.
Edit #3 (@ Michelle): I changed example #2 a bit, but if you see the abilities as too strong, could you tell me why? I see them as essential for the character to work as intended, but with adequate regulations to make it a very fair character. I also added a pure-combat example, which pretty much amounts to Teric Bloodrose at, I think, level 1 or 2? With a few more advanced skills, granted, but that's the point of the guideline. And yeah, I do think that we aren't quite nearly as nauseatingly welcoming as we all used to be, which probably accounts for it. We're so few now, though, that it's pretty hard to keep ourselves from leaving.
Edit #4 (@ Kyle): Zook pretty much answered your question the same way I would have. If anything, I'd just add that you could view these as 'more or less' level 2-3 profiles with some discrepancies. Overall, they're no more likely to powergame than previous characters of those levels. Skills can be powergamed only one way: by writing them stronger than they should be when compared to the skill of an opponent. No matter what regulations you put in place, that's the kind of powergaming that can't be prevented since it basically ignores what's in the profile. It's special abilities that we should be more worried about, but we need to keep an open mind and let people write what they want, and help them out when they make their mistakes. Learning this way does have its merits, and people are less likely to complain and leave once they understand by having slipped, than when they are told not to do something without being told why.
Edit #5 (@ Dirks): Not exactly sure what you're advocating, so I won't comment for now. It does sound like it goes along the spirit of the Guidelines here, though. It might be too extreme, but maybe if you explain your point of view more we might see it differently.
