It only makes sense to ban certain weapons when we view them as unfair, as the ones who possess them
not just view them as unfair when our enemies possess them.
2 times I had to fight against people who found Concrete Donkey (I haven't found it myself) and I felt like they really deserved to perform such an attack, since they didn't have anything strong throughout the match. Also notice that your opponent will never use donkey on you (maybe even throughout the whole match), if you always keep your worms close to your enemy's ones. It also helps to keep your worms spreaded horizontally, like me and danie did in our battle with Quaius and Gmaxus, unaware of their donkey possession.
Back in the days, in 2015 there were people saying "Ban clusters/banans from Tus Mole" "You can't win a match if the opponent finds clusters/banana" "Clusters are OP"
bull*hit... if you never expose the bottom of your worm you can easily survive a cluster on your head. If Clusters or Bananas were to be banned, then people would start dreading at the sight of strong Shotgun (which would begin to stand out from remaining weapons even more than cluster did. In the same way Aqua Sheep would stand out in Team17, if all Super weapons were removed). The problem is not with weapons, the problem is with one's hiding skill.
