There may not be much to complain about Bangladesh's bowlers but there are many complaints about the first-order batsmen because they never do well for Bangladesh.
You are right to say that there are many complaints about the Bangladesh team's first-line batsmen, It's very common to have complaints about them because they can never do anything good. While watching the match between Bangladesh and India today, I was very annoyed by Bangladesh's batting.
It seemed to me that as much time as it takes to blink an eye, bangladesh's batsmen were out even faster than that. All the teams in the group Bangladesh is in are very strong, so it may be the most difficult thing for Bangladesh to win any match. Bangladesh's margin of victory in this match should be reduced a little, then maybe there is enough potential for their net run rate to be slightly better than Pakistan's.
I don't understand why, two teams play on the same wicket, but when Bangladesh bats on the wicket, it feels like a bowling pitch, but when Bangladesh bowls, it feels like a batting pitch. Basically the wicket in Dubai where India and Bangladesh played the match didn't help the bowlers that much so the few early wickets Bangladesh gave away could be attributed to lack of skill and lack of patience. We know about the Indian bowlers bowling but the Indian bowlers did not get any extra advantage on the Dubai wicket, we did not see any swing or any extra variant of the ball, still I did not understand why the Bangladeshi batsmen gave away wickets so quickly. Had India batted in the first innings on this same wicket, India's score would undoubtedly have gone beyond 350 in the first innings. By playing cricket like this, the development of Bangladesh is never possible. Every team has a game changer but Bangladesh doesn't have that game changer and they don't have the chance to rely on experienced cricketers.
