Boogie, great arguments. I think your statements are strong and sound especially speaking about a future model for both games and gamers. I too would like to see EA possibly "remodel" their business profit into more consumer friendly trends.
The biggest problem I have with card advantage is field spell mechanics. For a while now, field spells have no longer affected both players, but instead the player who plays it. Classic cards like "Umi" affect both players by boosting all Fish, Sea Serpent, etc. atk and def on the field. Then you have "Dragon Ravine" that only affects the player who played it. Why can't the opponent use "Dragon Ravine" also because it's a field spell? Field spells are starting to become another spell zone.
