the game was much harder sets 1-13 and required much more skill, the cards didn't do "i win the game" always on them and the gap between good players and bad players was vast.
In today's game you can be vastly better than your opponent and still lose most of your games. too many cards give baddies a loaded gun to play with to shoot your opponent in the face.
the blocks/attacks and schemes are more obvious because of ninja combats and supports on their respective turns especially because of sasuke solo attitude. the game makes more choices for the player than the player makes for the game.
A lot of players that used to horrible and now topping events because of this. there is rarely anymore "mind games" in naruto anymore 80% of the time it really comes down to "do you have it or don't have it."
I miss the intricate complexity behind older naruto, where tech cards reigned supreme and showing up with a surprise deck could lead to win championships.
