If you're going to be pissy about the extra books then everyone else also gets to be pissy about how petty Jordan was. Taim was going to be Demandred as Jordan later admitted but because the fans caught on to how obvious it was rather than subtle hints that would make sense at the reveal Jordan changed things midway through the series meaning all the clues alluding to Taim being Demandred were just highly unlikely happenstance in the end.
This included their appearance despite the fact Demandred would likely use a disguise so Rand wouldn't actually recognise him, be that Mask of Mirrors, a ter'angral of some kind, or something else as there are obvious flaws to different methods.
The fact Taim used the phrase "The lords of chaos" in the book of the same name which is something only ever spoken by the Forsaken and other Darkfriends.
That Taim somehow knew how to train male wilders when his only excuse was "I was a False Dragon for a while until I fell off my horse at the same time you [Rand] proclaimed yourself 'The Dragon Reborn' and lost my fight".
Come the end of the series suddenly Demandred pops up leading the Sharan because Jordan's own notes cut Demandred out his own plotline and something entirely new was needed to bring him back in despite his prominence amongst the Chosen and vendetta against Lews Therin.
"I'm only about 70% through book 6, which isn't even halfway through the series yet"
There are only 11 books (+ NS).
There are 14 books. The first 11 were by the original author Robert Jordan. The last three (12-14) were completed by Brandon Sanderson.
There are only 11 books (+ NS). Trust me.

New Spring would be my guess which is a prequel set 20 years before the main series.
