I've been reading the books for that long too, proudgeek, and I've been trying to view this as a different turning of the wheel, but the storyline is completely incoherent, and so many of the changes show an absolute lack of knowledge (and care) for the source material that I've moved into hating it. The biggest reason is how they've fucked up Moiraine's character, and her relationship with Lan, plus the changes to the Two Rivers. The Cauthons being in an abusive relationship and the Women's Circle doing NOTHING about it? Whatever.
Emond's Field is supposed to be that bucolic life like the Shire in LotR, which makes the events of Winternight more shocking. Instead the writers have turned it into this grimdark horror in order to be more "mature", which is frankly the opposite.
Ingtar saying "Maybe he had a good reason" about Padan Fain bringing the Trollocs to the Two Rivers?! What nonsense.
The actor who plays Logain is ace, however, and is one of the best things about the show. And I agree that New Mat is much, much better than the original actor. Min is still cool, though the whole situation with her and Mat and Liandrin in the Tower makes no sense.
Merging characters is sensible - there were far too many with PoVs in the books - and I'm OK with Ishamael being with Suroth when we first meet her. I'm interested to see how they're going to bring the Aiel into it, considering how the storyline is completely messed up now.
WHEN IS THOM COMING BACK?!
