Natures have to be rigged for the worse

Not only did it take me over a dozen tries to NOT get a crap nature for my starter, but trying to catch a NOT crap nature for a teammate is just as difficult.

I would believe it to just be the roll of the die, but 90% of what I catch has a negative nature for the main attack stat. IDK how many tries it took me to find a Weedle that did not have a negative attack nature. Right now I am going for a female Nidoran, and ALL but one so far has a negative attack stat. This last one is Modest of all things.

Some people have not progressed because they are shiny hunting a starter, I am not progressing because I keep getting terrible natures.
