why change a formula with so much history and lore behind it... and why (spoiler for those that don't know)... have Belial, as "big and looming and threatening" during the summoner job quests... Seriously, if SE can create Belial to be so big, why not implement the egi-system, so that they don't take a backseat to the actual Summoner...

The Egi is the job... that's my understanding of Summoner... not the other way around... this entire system is broken...for the depiction in which it has been reflected.
