I'd like to propose that we should have less mini games during the barrows runs. These mini games would be helpful against botters every once in a while, but they pop up too often in my opinion. They bring a lot of hassle when you've already got your gear set up and you are ready to switch your prayer on and the next thing you see is "what is 10 + 9?" (not 21 btw lmao).
A second thing that in my opinion is pretty annoying is when you are playing in full screen and you accidentally miss click in your inventory, you start running into to place you "clicked" unintentionally.
