Even as Gandalf (the White) his powers are really basic magic like being able to do room-sized blasts of force, rays of scorching light, or darkness spells and then being a well trained and proficient melee combatant. They are overpowering abilities to the regular human fighters, or a Tolkien orc (which is basically just a more resilient and stronger normal real life human), they are sort of nothing in the context of Warcraft--a regular Kirin Tor mage can do all of those things, and also summon blizzards, throw fire, teleport people across continents, freeze people solid, throw shards of ice, etc. etc.
The same is true of Sauron. He beat but was severely weakened by fighting Elendil and Gil-galad, two people who, even with the rings taken into account, are probably weaker than more notable warcraft named NPC fighters like Nazgrim, or Taylor, let alone people like pre-corruption Garrosh, Saurfang or Varian. Sauron basically barely scraped through regular combat against two people.
I don't really see how he'd win against someone who can casually create ice storms, send out waves of disease and plague that can kill people in a matter of seconds, throw out blasts and bolts of shadow energy or summon pools of deadly shadow magic, call forth dozens of attacking spritis with the flick of a wrist, etc. Who is, on top of that, probably also significantly stronger and more resilient to damage.
Honestly Sauron would probably struggle against most high end NPCs, like Tyrande, non-Jailer Syvlanas or Thrall. We won't even talk about higher-tier characters like Jaina, who would probably absolutely shred him.
The base power scaling of the two universes are just too different on a fundamental level. Sargeras is not "in line" with Morgoth, Morgoth was, per the wiki, able to summon massive storms of fire, create huge craters, and destroy mountain ranges or fuck up oceans. Sargeras cut an entire planet in half with a sword swing.
