I agree that there is an imbalance. I mostly just play LI, PtB, and Patient with maybe a weird Isolation offense or LP thrown in there occasionally.
With that being said. This is the way the game has been for many many many seasons. Why have more people not adapted and started training shot-blocking more. In the USA we have a couple managers in D.II and a manager in the NBBA (Top league for USA) who have taken the time to train a lot of Shot-blocking and make that adjustment and they all have been fairly successful I would say.
This is similar to the free throws not getting cross training from jump-shot argument from seasons ago. Everyone seemed to complain, but nobody did anything about such as training free throws even once a season to help their players. Now this isn't a problem anymore as BB made a slight adjustment, but I think it is fair to say that not enough people are adjusting to the game the way they need to.
People fall into the LI mold because it is easiest, but teams have been very successful doing other tactics and winning. Additionally, if you are facing a team that can do nothing else effectively, then you can easily use GDP to help. I feel like people are so scared of being wrong, they rarely use GDP.
Ultimately, you are right, I'm just saying managers are slightly to blame as well. MÅ‚oty Stargard has won the last two B3s and is probably the best manager in the world. This is his offensive tactic distribution the last two seasons in B3.
LI - 12
LP - 6
Motion - 4
Patient - 3
PtB - 1
RnG - 1 (was used in the B3 final to win in s44)
LI used 44% of the time
Other tactics used 56% of the time
Just something interesting I thought I'd bring up.
