Which one would you rather have:
A quickly churned out, unedited chapter that gives you characters that are flat and dull, terrible grammar and descriptions, and boring plotlines?
Or would you like to wait for a chapter about once every other month on average that gives you brilliant characters that feel like you could meet them in real life, descriptions of scenes that let you feel the wind in your hair and smell the surroundings, and plotlines that grip you and make you quiver in anticipation of the next metaphorical page?
Be patient.
Also, just because this is something that REALLY gets my goat:
Novels, in real life, take years to write, edit, and publish. And the people who do that often at least do it part time, and get paid for it. Dunkelzahn is making this wonderful piece of art on their own time and money, and probably have a full-time job to worry about too. They could be using their time more to their own benefit, but they choose to use it to write this instead. They don't owe anyone a 'fix' of their wonderful Fanfiction. Heck, they could drop off Questionable Questing entirely and there's not a damn thing we could (or SHOULD) do about it because that's THEIR CHOICE. It's their choice to write this fanfic, it's their choice to not write not write this fanfic. So, please, don't annoy them for another chapter.
