it takes hundreds of crystals and brainwashed beastmen to summon the primals, hell even beastmen sacrifices ... you are just 1 person with a book on how to harness a fraction of the power from the primals that reside in hydaelyn aether.

ill take my egis + lore over "look at my primal i control it, im allmighty --e-peen--" any time of the day.

also in FFxi you made a pact with the primals after defeating them. here primals are not going to serve you, they are the gods of beastmen.
