I just spent a couple of minutes rumaging through 2headeddragon and i realized something. the amount of characters each symbol has mater. life has the least chars(35) and is the worst symbol. I was just thinking that the most chars=the most suport, and the most options. if the rate of good characters to bad characters for every symbol is the same shouldn't the symbol with the most characters be the best symbol? My theory isn't conclusive. order has only 38 chars, but chaos and fire(as of set 12) both have 53 and are both very good. The next most is air with 48. death has 46 and in my opinion is on the rise. good has 42 (with Jt) and isn't very good straight, but is a good dual option and shares a lot of cards with air. All is next with 39(with jt) and is weakening. earth and order are next with 38. void has 37 and is on the rise. water and evil have 36, and both of them are hurting (less so for water). and life has a mere 35.
Maybe it doesn't matter, but like most wacky theories there apears to be truth in it.
