A basic primer on argumentation by Cless.
I don't know whether or not you have the time or motivation among anything else to make this happen, and I was not questioning your contribution of time and effort to the server thus far; I do understand how these could possibly be limiting factors, however, especially if I was using me as a model.
I'm not going to argue about broken content or whatever. Suffice to say that a large portion of new content is tweaked shortly after it is implemented, and that guilds like <Twilight Underground> and <Fair Weather Friends> are basically beta testers for new content, by their own admission.
Either way, you cannot deny that it has resulted in at least a few disgruntled players, some of which have quit as a result.
So, the rationale of your last several posts has merely been to state three things.
(1) With an infinite army of competent volunteers doing nothing but working on stuff, there would be plentiful amounts of content, all perfectly balanced.
(2) Any imperfections in content is due to the lack of numbers, will, drive, motivation, skill or time of the devs.
(3) These imperfections inevitably cause(d) people to leave SoD.
Alright, I grant these as facts. What does this have to do with your previous statements?
There's no reason that two mostly separate sets of tiers cannot coexist outside of things like -- disregarding possible client limitations -- time, resources, motivation, and general will. All of which probably are not present and never will be convenient for the unpaid staff of a free game, but that doesn't mean it's not a possibility.
It seems you are implying that there is some finite, even if prohibitively large, amount of effort that could create this tier dichotomy to general satisfaction. However, you merely state this fact as a given with no supporting evidence. In contrast, I can guarantee that virtually all of the mccoys and staff disagree with this assumption based on mountains of evidence and years of experience. I feel no need to provide this evidence, as any responses generated by this discussion should do so for me. Also, feel free to ask them and find out for yourself.
Given that "virtually all of the mccoys and staff disagree with" the statement "[t]here's no reason that two mostly separate sets of tiers cannot coexist", no devs have created of a 6-12 man mid-tier progression path. Furthermore, our own research would suggest that the creation of such a path would only worsen the problems your suggestion was intended to remedy. Since you provided no evidence or argumentation that actually supported your claims and suggestion, your suggestion was rejected. Any further gainful discourse would require the aforementioned.
As a bonus for reading this far, here are a couple tips for improving your posting experience (and by extension, mine).
(1) Assumptions should be backed by reasoning, evidence, or general acceptance. Anything not backed by these is a "premise", and therefore treated as any other hypothetical. Any argument based on any premise is not valid for actual situations, so do not attempt to use them for such purposes.
(2) All the staff here are unpaid, dedicated volunteers that give up their free time to work on making SoD that could otherwise be used in actually playing the game. Also, all staff members were picked from the playerbase due to their talents, dedication, work ethic, playtime, reputation, and character. Even after one becomes staff, one is subject to further, even deeper scrutiny. So any staff member you see is absolutely beyond reproach in their worthiness for their role, and should be treated with great respect. To say something intentionally hurtful, especially like "Yeah, you might as well just quit. All your content is fucked, you never fix anything, and you always break everything." is reprehensible and unacceptable.
