My reason for not relying on the list is as easy as that: having one good eido doesnt guarantee them having decent eido for every element nor that they will ever get decent eidos for every element if they dont have them yet.
In my case the guys that dont have 0* eidos in the first place often have 1 decent eido and run extremely weak and unhelpful eidos on their other elements.
Starting a Thread here just seems like a more reliable way to get friends with decent Eidos.
