I dislike Paolini, for reasons the original post touched on rather thoroughly. The only other author I can say I don't like is Richard A. Knaak. I have yet to read anything written by him where I could bring myself to care about obvious self-inserts, Mary Sues, and villain-of-the-week plots.
I've successfully purged all memory of his work on Dragonlance from my mind, so let's look at the work he's done with Warcraft lore, using it as toilet paper to wipe his Rhonin fantasies on. First and foremost, Knaak turned the War of the Ancients, a major turning point in night elven culture and history and arguably the beginning of high elven culture and history, into a time-travel adventure just to continue showing off how awesome his pet Mary Sue/self-insert Rhonin was. He even went so far to have Rhonin teaching Illidan Stormrage magic, backtalk to night elves in high positions of authority (something that, back then, would have gotten anyone else executed). Oh, did I mention that Deathwing compared him to the Guardian Medivh, he marries a high elf girl (a Windrunner at that), has several half-elf children against the odds (high elves have a very low birth rate to prevent overpopulation, thanks to long life spans), and out of nowhere replaces the leader of the Kirin Tor (who was in Alterac/Dalaran overseeing reconstruction)with nary a line explaining how?
