In regards to the above points:

-I doubt Artanis was planned to be possessed by Amon - you wouldn't do that to an established character. My guess is that the story would be similar, but you'd have Artanis as a de facto Khalai representative, since many LotV protoss characters effectively represent their kindred in some form. Having Zeratul as the protagonist still wouldn't negate the presence of Vorazun, since Zeratul at this point is a lone wolf.

-I actually liked the idea of Tassadar being the Twilight Messiah, of coming back in some form, but not so much in physical form (he'd have to be in physical form to have his nerd chords cut). The whole "it was Ouros all along!" thing reeks of a change, as there was no real hint that it may not have been Tassadar up to this point. Also, Ouros/Tassadar states "I have never tasted death, nor shall I," which we know by LotV isn't the case, since Ouros does die, and never pays lip service to this declaration (not that xel'naga have lips).
