What I would rather have is that BCB divides the zone according to the NCL team and prepares different wicket in that different zonal area.
For example, Sylhet could have seaming bouncy pitches while Rajshahi can have spinners slow and low. Let Khulna, Barishal be a batsman's paradise while Dhaka, Chittagong could have sporting pitches that favours everyone. ( Just as an example).
This way, with 8 teams on a Home and Away league system, each team will face their favourable and opposing conditions with something for both bowlers and batsmen.
When the players groom up like that, no matter which part of the world you are traveling, you would be better prepared to face the music from the opposition team.
But nonetheless, this initiative of preparing sporting pitches is a good one.
Verily, in the remembrance of Allah do hearts find rest [Al-Qur'an,13:28]
