Wildbow didn't state that. In fact, he's compared GRRM's issues with later GoT books to the fact that GRRM needed but ultimately decided against/was forced to avoid a timeskip.
Wildbow stated that the timeskip suffered for poor execution and a lot of IRL stuff that was going on at the time (including a semi-forced 2 week break from all internet/computer stuff mid-arc), and he intends to rewrite it and cover different bases for the published final version.
Hey, since bumping into this thread (have read much of HPMOR) I decided to check out Worm and it's excellent - have read ~1000 pages (out of around 10K on my device), half on the site and half on, for convenience's sake, an ebook version I found floating around. I'll be donating in a second here, but I really would rather (for whatever reason) have made it a transaction and bought a copy in some legit epub or mobi form from you, the author.
It's a bit late to hope for a response, but I'm somewhere around 7.08 - should I wait for a revision or just read on and revise my opinion later? At any rate thanks for writing and I hope you get the book deal you very richly deserve.
