Not as much as Yamcha.
He was used to hype up Jackie Chun in the 21st TB. He was used in Baba's Tournament to show off how strong her minions were and how strong Goku was. He was used in the 22nd TB to hype up Tenshinhan, then in the 23rd to hype up God, then in the Saiyan arc to show off how dangerous the Saibaman were and to set the mood for the arc and then used to show off how strong Gero was. He was always Toriyama's go-to guy to show off how powerful the new mysterious character was and it always resulted in certain humiliation.
for what? Only piccolo did stuff in the buu saga important compared to the other b team Z warriors.
You misunderstood. I said that by the time the Boo arc came along, Yamcha's credibility was so low that they had to use Piccolo and Kuririn to hype up the new threat, Dabra in this case.
not really just because they all get beaten up by a villain to show of strong a villain is isn't Yamcha's singular role in the show.
His other role was to provide exposition. That's it, something Gohan has done and can do.
Yamcha was forever last place, Gohan isn't, Gohan will always be a strong character (not first or second ever mind you) no matter how far he'll fall behind in training. its not like Gohan will become so weak that krillin, Tenshinhan, yamcha could bridge the gap in strength.
Last place? He's stronger than Roshi and Yajirobe, mind you.
No, but Gohan can easily become the weakest Saiyan, maybe even weaker than Piccolo, and he was the strongest at one point.
Kinda like how Yamcha was only second to Goku back when he was introduced and now is one of the lowest.
