Level 5 is a big head start the the start of the world. but by the end fuel and bricks just make up ore Q to easily.
I don't think 5 needs to be nerfed.
if you still wanna be ahead. the highest Q of ore will still be needed.
you're not competing with the pro's currently of major realms.
also not everything should be easy once you level past a point.
slimes were a great add.
people need to fk off with trying to nerf it.
