So, I think it can stay even though it is quite overpowered, but I think you can take measures against it, you can be the first to just use your building skills to combat it. You can make a anti-knockback bridge, I understand that it will take long but it's the part of the game in my opinion. In Overpowerd you can buy an Enderpearl. You can also just buy a shield.
I don't really like to see a change that the Punch Bow will be a higher price. They already changed it back in 2017 I believe, I think most of the people were happy and so me. I think if they change it to 40-50, it will be too expensive I think.
Normal = A Shield costs 30 Diamonds.
Overpowerd = A Shield costs 10 Diamonds.
It is also in 1.8, but you can't buy a shield, you can build a anti-knockback bridge or buy an Enderpearl.
Also, please add a poll, I think it will be useful if you can see what people think is a good idea Yes or No.
