Dragons (Specifically, the Brown One)

Just to get this out of the way, I love the new dragon system (that was most definetly not inspired by Avatar: the Last Airbender).

The fire nation is allways blowing stuff up and saying stuff like B*TCH GET TORCHED, which is what the fire dragon helps you to do. Its a great not-fire nation.

The water nation is kind of healy, with their magic water and stuff, which is what the water dragon helps you do. Not as great a not-copy, but it's pretty good, and a healy dragon is kind of required.

The Air nation is very mobile (especially when they get on their scooters/gliders), so the air dragon is a perfect fit.

But the earth dragon doesn't fit the earth nation as well. I personally feel like the Earth nation was more known for building massive walls and laughing at people who tried to break them, instead of whacking other people's walls; the earth dragon seems to be more focused on blowing up other people's towers.

Basically, why not make the earth dragon buff your teams towers (for example, more damage reduction, or just flat health bonuses), to make them approach the power and might of Ba Sing Se's great walls.

Also, this would help that whole damage creep/tower diving thing that people are whining about, which is nice. But really, I'm just in it for the alignment with its not-inspiration. :)
