Have to say, this was a bit of a letdown compared to the first few games, which were MUCH better in my opinion. Returning to the simplicity of the first few games instead of the clutter, the absolute need for grinding, and lack of quality settings for those who need it (and the need to hold the speed up button... just... why?) would make the game more enjoyable.
Anyone who has just started the game and needs help to make a good deck, don't go asking what's the best element. Every deck has counters, so there is no best. Also, read this for good starting decks: http://elementscommunity.org/forum/index.php/topic,49513.0.html
