Is there a good reason why the developers of SG didn't include the earth element? Other than having a neutral element, it can be converted to earth so that the circle of elemental chain will be complete... I grew up watching A-LAB (Avatar - The Last Air Bender) and seeing the element thing in SG made me bond to the game even more, now the deprivation of the element makes it feel... incomplete... that being said I'd like to know why there's no earth element...
