For those using Sargeras size from the ingame cinematic at the end of Antorus the Burning Throne raid...
What's your opinion of Medivh?
He was meant to be the most powerful 'thing' upon Azeroth and yet he was just the size of an average man? I have NO DOUBT that he could make himself look bigger with the power he wielded but.
I find the whole "Sargeras is bigger thus stronger!" Discussion to be quite testosterone filled...
There are countless times where significantly smaller individuals have defeated significantly larger entities.
Ex: Ancalagon the Silmarillion?
FF14 that big dragon vs that old man?
(Dunno don't play FF)
And as others seem to of stated in here and it does make sense to me.
The "titans" is just the title for the leaders of "Order" they have equivalent counterparts in the 5 other realms of order.
Otherwise why isn't everything that exists following 1 specific order because said 1 of the 6 is more powerful and defeated the other 5 order realms?
