>>50037855Those Pokemon are the """staples""" because there were literally no other Pokemon available early game (minus gen 1 filler), dipshit. No other region has the problem of everyone using the same Pokemon because other generations have way more available earlier in the game. Gen 3 for example has a massive amount of Pokemon for you to get before the first gym and surprise surprise, the team variety is way better. Gen 4 also has the highest amount of dumb gimmicks needed to get Gen 4 Pokemon but that's a separate issue.
To fix Gen 4's Pokemon variety you'd need to make actual Gen 4 Pokemon (or Pokemon with cross gen evos) available in place of kanto filler trash.
