Instead of speed runs they should have it set up with multiple paths. easy, med , hard.

Easy path can only be opened by a light party with very low chance of "blue" loot draopping

MEd path is for light-full parties with low chance of "blue" dropping

Hard path is for full PT only with average chance of "blue" dropping

take speed run completely out of the equation and add difficulty to the dungeon. If it takes a party the full hour to complete a hard mode dungeon they should be rewarded for the success of the clear. Not the time that they did it in.
