The 4th War was screwed since the beginning

The War of Thorns was an idiocy even before the army of the Horde moved from Orgrimmar. Not speaking about a voiced idea behind it... Who the hell decided that walking by feet from Orgrimmar to Silithus is a believable thing? I hope Blizzard realize it's much longer than in MMO (because game mechanics). You need to travel across:

1) Durotar (possible but kinda arid)

2) the Barrens (possible but still a bit arid and inhabitants are embarrassing)

3) Thousand Needles (lmao good luck as it's flooded and connected only by a bunch of rope bridges)

4) Tanaris (a freaking desert with bugs)

5) Un'Goro crater (swampy jungles with huge aggressive dinosaurs)

By feet. Across almost the whole continent. A large army marching through these perils. And it must carry food, water and other supplies (also because it would be impossible to obtain it in place). When it's possible to reach by fleet (what is much faster). Logistics? Sorry, what is this?

I wonder do Blizzard think that the Alliance are so idiots to believe in this, the Horde are so idiots that it could be a possible decision for them or both?
