I’m mostly worried for the Easter Eggs in the levels. While I liked that they swapped bandits for orcs as a little touch, I don’t think it was as good as the Zoo. This, and some of the secrets (like the Secret Level you unlock in the Blood Elf prison level) were (imo) vital parts of making the campaign interesting, and made you explore the levels, rather than just blitz through them. (I’m fine with minor cosmetic changes to make the level designs smoother/more defined, so long as the actual levels are faithful to their sources. I just don’t think you can make significant changes to the reasons people do things/what order they do things in, and not diminish the story).
Also, if I remember correctly, Akama mentions that he is some of the last of his kind, being hunted to extinction by the Orcs. So making him just a variant to the Draeneis pretty much undercuts his entire backstory.
