Fixing random seed speedrunning

Minecraft speedrun community is pretty big one, and I have some suggestions on balancing out random seed speedrun.
1) For the first hour since world creation each blaze will drop a blazzing rod, and Piglins trade 8 pearls only on each 10th trade, which means you'll get all pearls you need on 20th trade. By doing so, players will get some consistancy, and it'd be impossible to manipulate random chance 
2) Random seed is about luck, but also - about adaptiveness. With consistent drops it'd be great to host small tournaments with speedrunners who speedrun the same random seed, best summory time of three seeds.
