One of the worst book to series adaptations ever created. There was no sensible reason for the drastic changes in plot and characters they have done. Wish they would cancel and retry it with some other creative team.
Book spoilers ahead:
Look, I get that Loial can't be as big/tall for obvious reasons (budget, that CGI would be heavy) and I get that we skipped Caemlyn for casting reasons (can't really have Elayne/Gawyn/Galad/Morgase/etc show up now only to disappear for a season or two) but the whole "any of them could be the dragon" or "they could all collectively be the dragon" was annoying. Look, I'll be the first to point out the sexism in the books, the women fawning over men they have met 1-2 times, acting like love-sick puppies, etc but I'm not really sure that pretending one of them could have been the dragon is the way to right that wrong, if that was even the intention (also, to my understanding, the dragon is always male because of Saidin. I was also under the impression there has only been 1 previous "Dragon", Lews Therin Telamon, but the show acts like there have been many?).
The waygates really made me angry, where is the leaf of Avendesora? Literally every time they go into Ways we get a few lines to a paragraph describing the door and how it's opened but in the show you have to use the power to open it? How the heck is Loial supposed to open it when he, Perrin, Faile, Gaul, Chiad, and Bain supposed to travel back to the Two Rivers seeing how none of them can channel?
