It is entirely wrong.
No it is not
Medieval, as per definition: relating to the Middle Ages.
Resembling or likened to the Middle Ages, especially in being cruel, uncivilized, or primitive.
Especially medieval europe in your example
Warcraft: Orcs & Humans (1994): For ages, the fallen titan Sargeras plotted to scour all life from Azeroth. To this end, Sargeras possessed the human sorcerer Medivh and compelled him to contact Gul’dan, an orc warlock on the world of Draenor. There, Sargeras’ demonic servants among the Burning Legion worked to corrupt the once - peaceful orcs and forge them into a bloodthirsty army known as the Horde. This cursed force invaded Azeroth through the Dark Portal, a dimensional gateway created by Medivh and Gul’dan, and clashed with the human nation of Stormwind.
Now, I give you that, the original setting in 94’ was quite “medieval”, tho’ I would argue, when there is another planet and alien invasion, that is actually Sci-Fi territory, but the two could co-exist. It is a bit like Speljammer of D&D
But when 1995 Warcraft 2 and '96 the Beyond the Dark Portal came out, we had Dwarven Demolition Squad and Goblin Sapper units, Gnomish Flying Machine and Goblin Zeppelin, Oil Tanker and Oil Rigs, Gnomish Submarine and missle equiped Giant Turtle…
Things that are massively steampunk + the travelling to other planets, sci-fi element again, but the european medieval setting was out of the window
Warcraft 3 came in 2002, and expanded our repertoire with Laboratories, Goblin Shredders and Tinkers, Dwarven Riflemans and Mortar teams we were neck deep in the steampunk
World of Warcraft is full of Gnomish. Dwarven and Goblin inventions (and weapons) centered around steampounk, rayguns, rays of various kind (shringing, X-ray, etc) technology, Hi-tech even, with the sentinent robots (and not quite sentinent ones) they build from rusty metal, mech suits, teleportation chambers and securtiy systems
Nothing bad in it, mind you, just calling or comparing Warcraft to medieval fantasy (especially europen medieval) is damn hard, when they are capable of technoloical feats that are not even possible in the 21th century
As I said, Warcraft is more like a steampunk High fantasy with heavy Sci-Fi elements heavily built on originally the Warhammer theme
