Just wondering, why do u need those elemental books? Sage proff has endows, for a SG doesnt matter since they too have warm wind. So any element wont matter right?
Maybe if you're making a +10 elemental book you want to use all materials you have available.
a +10 lv 3 weapon with 90 ATK would be nicer than a +10 lv2 weapon with 85 atk for sure.
As you (probably) know every +1 on a lv 3 weapon gives more ATK than a +1 on a lv 2 weapon
Anyway yes talis said he was going to fix the fire one but he never said when so who knows.
