What is the difference between the powerful fire element and the earth element of the shaman in World of Warcraft?

Earth elements eat hatred. The totem hatred of the earth element was immediately robbed when the BOSS was hit, and the blood was 2W8++, and the armor was also high, so the earth element could be temporarily supported when the T fell. Fire element, pure legal system BB, flame nova AOE is also very strong. When AOE, you can open one to improve DPS, but you don't eat hatred. Blood is only 1W++, which is brittle, but immune to fire spells.
