I can see why youngsters wouldn't want to be fast bowlers lol with the pitches they produce. IMO, Al Amin and Robiul have to be the 2 seamers that lead the attack for the near future anyway, with someone else as the back up 1st change. They're not great, but the best they have atm.
The batting is fine and it's a long batting lineup as well which always helps. Maybe Imrul Kayes was always meant to bat at 3 lol, as he had a shocking record as an opener.
They'll always struggle to win tests with their lack of quality pace bowlers and the roads they produce, but they're becoming extremely tough to beat at home which is a sign that they're slowly heading in the right direction.
