In my opinion, I feel that the current rule set works pretty well.

If there's one thing I would change, the best rule for me would be:

• Kits should be allowed for every single run. If a kit already has the required item (such as Farmer going for Egg%), the run wouldn't count. The kit can be used to assist the player, but not to instantly complete it. That would be Pyro for "Lava Death" would be completely fine, as the kit is assisting the run, rather than completing it.

For the category of "Highest Possible Position", the user VirtualCoins is currently holding the record of 00.02.220. After attempting to break this world record, I have tried countless of times using the exact same strategy. After being off by a few milliseconds every time, I decided to try and time the user's run. After timing it, I found that the actual time was 00.02.335, which means that the run was timed incorrectly.

Evidence:

... So does that mean my run can be approved? @ReverseDmitry

In the category of Lava Death, the rules state:

"Die in lava. Can be done in every mode. Can be done in a party. Timer starts after freeing the cell and ends after death."

No where in these rules does it mention you can't use kits, though I was rejected for the reason of "Must Use Default Kit"

For the speedrun of "Obtain Fire Iron Sword", my run was rejected for the description of "Use Default Kit". In the rules, it states:

"Obtain an Iron Sword with Fire Aspect I from a chest at middle. You may not craft swords, nor enchant swords. This must be done in Solo Normal or Teams Normal mode. You can be in a party."

There's no requirement about having to use the default kit, though my run was taken down because of that reason.
