@AlenEdits he means he wants to discuss a buff for barley because he feels throwers are hard to play.
Personally I agree with @TeleTrickster. Barley needs no buff.
@Susanlovespokemons I feel from this discussion that what you need is more practice, here are some tips:
First, Barley is a thrower and so he is meant to stay away from enemies with a wall in between you. This way you can attack them but they can't attack you. Throw your attacks to where your opponents will move, not to where they are now. That will help you land both of the ticks of damage. Hopefully you have better luck playing Barley in the future!!
