In theory, Yogev's idea felt like it was going to be successful in real life however when they started doing it, he realized that the mages weren't that strong, after all that spell was made by the higher-ups, it was impossible for them to be anywhere near their levels of powers.
And then being left out here is the reason what got him to think that way .
The mages were lined up around the huge castle making a chain of people trying to maintain the equilibration of their divine energy .
To him, there was no other way to prove to his people that he was ready to help them then, and that is why this was his main focus all the time.
This new method was very promising in theory because the majority saw that it made sense and it was more realistic, however, their powers were very low from the beginning which delayed any results.
