I agree 100%. And, as I said in another thread, it is important to point out that we have not yet had the time to "create" players/teams built in order to specifically utilize that particular defense tactic. That's why I believe it is immensely important not to make any further "improvements" to 2-3, at least not at this time. It looks promising enough to me right now.
