Our server changes daily, and we have a lot of custom items, and the problem behind your idea is, that we will always have different opinions about the builds, hence you won't get any consense in order to create one master guide.
For example for Snipers: There are people using Luk in order to have higher Crit, to strengthen their FAS dmg, or regularly just with Dex, and people will always argue in favor and against one of these, so the only way would be to make alternative builds as 'master guides', if that's what you mean, then I can agree to that.
