1. I don't like having potions as an item you can buy at the shop, it just doesn't feel right to me.
2. Fishing rod in 1.9 is useless and the pull feature could be very overpowered.
3. I don't want to have a ranged poison pot. poison in general is annoying since it makes jumping a bit weird
4. Too overpowered & will cause anti cheat fighting speed kicks. Might as well play 1.8
5. Ladders can prevent all fall damage & can be used as collision traps
6. Players are allowed to have minimaps, so this is pretty much useless. Most maps you already know the layout of, and maps require you to visit the terrain to load/update the map
