Elemental is very nice game, but i think need some upgrade for better fun.
1 More magical def/attack ratios for troops/monsters/faction/heroes
Example:
A Fire elemental need more resist against fire magic, but sensitive against water magic.
Or factions: Amarrians resistable against earth damage, but sensitive against physical attacks.
etc.
1. More optional weapons/stuffs
Such as mage staffs
Bows
etc
Example:
Small owl ring +1 mana
Great owl ring +2 mana
Small wizard staff +1 mana regeneration/turn
Great red wizard wand +5% fire spell damage
Great blue wizard wand +5% water spell damage
Longbow of Speed 1.25 attack speed
Longbow of Cloudy Sky +3 air damage
etc
And other thing all faction have all magic, i think it's not too good.
Should be better, f they have specializations.
As:
Peoples of Dark Nations
Specialized to Death Magic
Who live at water, specialized water magic etc
