Pokemon Go truly is the worst balanced game ever

The pokemon blue/green/red where better balanced then GO is. And they are over 20 years old and yet they manage to just make this worse then them, HOW. They could have just done the exact same thing and it would been 10x better,
 Just look at Flareon, Vaperon and Jolteon. Why is Vaperon so much stronger? Why can it beat the its weakness to lighting easily. The game is just so bad.
