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, If they can do that properly maybe their net run rate will be a little better than Pakistan's.
To watch Bangladesh matches, you must have the ability to control your anger, otherwise you won't be able to watch Bangladesh matches. I stopped watching the game on the television screen when Bangladesh fell for five wickets at 35. Later, I saw the score on my mobile phone on Cricbuzz that Bangladesh were all out for 228 runs and there was a happy news that Tanjid Hasan had scored a century. However, if you want to watch Bangladesh matches in the future, I request you to watch the matches with the ability to control your anger.
