Since the start of Dragon Ball Super, the power scaling in the franchise has gone through the roof, largely due to a new type of energy called God Ki. This is used by Divine Beings, is largely invisible to mortals, and is the primary power that is currently used by Goku and Vegeta in the modern day.

The introduction of God Ki was crucial for the continuation of the Dragon Ball story, as it allowed many new types of fighters to emerge who existed at much higher levels than any in the franchise's past. However, as a result, many of those who are unable to use this power have become utterly forgettable.

The most powerful Legendary Super Saiyans in Dragon Ball are warriors unlike any other, capable of fighting non-stop.

Yamcha is often remembered as one of the most iconic punching bags in anime history. Although he started off in the franchise as a fairly notable bandit who learned some pretty strong techniques, his overall power and influence on the story would start to wane from there. Ever since the dreaded incident with the Saibaman in the Saiyan Saga, Yamcha hasn't been the same.

Ultimately, although it can be concluded that Yamcha has, in fact, been obsolete since the introduction of God Ki, the truth of the matter is that he was largely out of the picture long before that, ever since the days of Dragon Ball Z . Because of this, Yamcha has given up the life of a warrior entirely in order to pursue a career in baseball.
