I must say don't like it too much because most swaps feel extremely cheap and low effort - like orcs still living in human cities (you could add Orgrimmar style orcish structures instead of human farms and mills) and human "plague" turning orcs into humans (couldn't humans simply capture orcs as slaves instead? Then they would have a much more believable Blackmoore-style vibe).
Also, Northrend turned into a concrete jungle with irregular cliff shapes and wild grass just replaced by cityscape lawns just looks... bad. It feels like a nightmare of an urban activist who fights to protect green areas in the city from developers wanting to cover everything with concrete

.
Gameplay-wise it looks decent, orcish techtree seems fine with some changes like tauren riflemen, humans also got some new toys like Gunships which is always a welcome sight.
Also, I will forget all my critique if the Highlord of Humanity turns out to be Lord Garithos and the Path of the Rightous will be purging lesser races in his name
