I think you are missing a crucial point to build advice from people.
Not only is it that builds must be level 20, have all 200 points, must have basically all skills, but it is to state that these are the skills, weapons, armor, point allocation, and perhaps even the way skills are layed out that you should be gunning for.
As a player who just created a character, then asks for people opinion and advice on how to make a good character (either solo, PUG friendly, PvP, etc.). People will give advise based on their knowledge. Usually its been so long since they had a beginning character, they have forgotten what skills they had access to, and how they were able to "do well".
Trying to make a step by step build (level 1, have this, level 2 have this, etc.) is time consuming and hard to remember. Most of us like to forget our "noob" experience, and our adolesent characters.
I doubt you'll find someone taking their time to document from level 1 to level 20+ in a step by step build. I think you'll get bored after the first paragraph.
I have both, but I try to give advice on Factions only or Prophecies only. Sadly, I don't really know what if Factions only though.
But people should state that you only have Prophecies or Factions or want builds only for PvP, PvE or whatever. If these are not stated, then either no one will give advice, since they don't know what you want, or they will give advice based on what they they want (PvE, PvP, Factions & Prophecies, etc.)
Hope this helps in your understanding on advice given on builds.
I understand that a person trying to make a suggestion may not completely understand what skills others may have and at what position in the game they are, but its a bit annoying to read build advice that is completely unapplicable because it makes the assumption that you can load whatever skills that are suggested.
