What I don't understand is how a Naaru can be the equivalent of the Old Gods yet would probably lose in a 1v1 fight. Same with Arcane and Fel, how can they be seen as equal when Fel is stronger?
Call me stupid or smth, I just don't get it.
Fel is stronger, but more resource-constrained and less controlled. Brute force vs. finesse. We've never actually seen a fight between a Naaru and an Old God.
The Naaru can also be equivalent to the Old Gods without any individual Naaru being a match for an Old God.
