To Put it Simply, I HATE THE UI OF SPELLS and I HATE THE WAY SPELLS ARE BEING RESEARCHED.
currently, all the spell books are marge together when you do researching magic and spells.... so all of the spells are merge together in one Big book that you have to flip around to just to find a spell to cast in battle or map.
how this is a problem? look at it this way..... you have to research each spells individually or just research the next level of spell. to me this doesn't really make any sense and it's hard to navigate in one big book.
I would really like if we could research each type of books of spell individually in-stand of all the spells in one book.
here is an example of how I think elemental spell book should look like.
-------------------------------------------------------------------------
Fire:Lv1 book:x x x x x x x x x x
Lv2 Book:x x x x x x x x x x
Earth:Lv1 book:x x x x x x x x x x
Lv2 Book:x x x x x x x x x x
Air:Lv1 book:x x x x x x x x x x
Lv2 Book:x x x x x x x x x x
Water:Lv1 book:x x x x x x x x x x
Lv2 Book:x x x x x x x x x x
Enchantment:Lv1 book:x x x x x x x x x x
Lv2 Book:x x x x x x x x x x
-------------------------------------------------
each of the x represent a spell,
normally you have to research Lv1 of one of the spell book to able to use that spell book.
The way I do it is, each spell has a %. if you add up all of the spell in lv1 you get 100%. If you research all of the spell in Lv1 to 100% you can now able to research Lv2 spells. and so forth. this would make a lot interesting game play than the current setup, and you don't need to wait to use your LvX spell before it's completely finished researched.

I don't like the way hero or champion need Sovereign to channel their essence in order for them to have mana to cast spells.
alot of monster in the game have mana but they can't cast spells. Heros should have mana too by default. How much many each of them get depends on each hero.
Sovereign essence shouldn't be used to give mana to hero.
The more essence the Sovereign give to their hero, the more higher level spell the hero can cast.
for example I give my hero 1 essence, now he can cast lv1 spell from one type of my spell book. If I want to make a fire mage hero I can just give 1 of my essence to my hero and give him the abilities to cast lv1 book of fire spells. Later on if I decided to, I can give him more of my essence to allow him to cast summoning spell from my summoning book or I can have him increase his fire book spell level higher to make him deadlier.
