Well I might as well put this in proper format.
Aether is #1 purely because it has the coolest icon, nothing more.
Entropy is next because Butterfly Effect is so... perfect.
Earth is #3 due to the awesomeness that is Earthquake.
Fire gets fourth for the sweet speed and control. Blazing fast! Get it?
Darkness for #5 because of the large amount of control that it offers, it is also just cool looking.
Death and Time are in the middle because, even though Time is my favorite Element,
the lack of permanent control really starts to take its toll.
Gravity is #8 because of... well I just don't like it.
Life is next because of no control, and I am not a fan of Life in general.
Light gets #10 for Hope, but that is really the only thing it offers.
Water is just bleh, even though the master is the coolest guy on the forums.
Air is just mediocre.
