Except it really isn't. To isolate players EVEN MORE than there is already in the Pokemon TCG would be a HUGE mistake. If you look at any other TCG there are cards that you can play during your opponents turn, and have more interaction between players. If you get rid of N, then what you actually do in the game matters very little. It becomes about if you draw your cards. Deck building and gameplay become far less interesting, and dominant decks (BDIFs, OP decks, etc) become far more prevalent. When you can't do ANYTHING to disrupt your opponents strategy, the game just becomes stale and boring. Sounds like you just hate being punished for being overly aggressive.
