I still don't get why everybody keeps lumping earth in with destruction. Sure, it may be cardwise, but in reality (which is what these should be based off of imo), the Earth isn't really destructive. I mean, it's the only planet thus far discovered that could support life...
I agree wholeheartedly--earth is a more about order than decay. Clay is malleable and can be used to form just about anything. Of course, we're not the first people to have these thoughts: "Then the Lord God formed man of dust from the ground, and breathed into his nostrils the breath of life; and man became a living being."
In fact, if you look at the OP almost everything fits pretty well except the 2 elements that could easily trade places are
and
. (To be fully honest, it wouldn't bother me if
and
were switched too, but it's not as glaring a problem as earth and water.) Sure, water is essential for life, but it's a pretty destructive/erosive force. Think about rain eroding soil, a tsunami wiping out everything in its path, waves crashing against the rocks reducing them to pebbles and sand. That seems to be a better argument for water as decay and earth as order.
Yeah, I know, not perfect. But better IMO.
