Not really, just as Piccolo can instantly destroy moons in the anime he can can in the manga, I've read the manga and in fact the anime does it little justice sometimes as the fights are wayyyyyy slower on the anime, for example Goku vs Frieza and Gotenks flying around the world, in one panel Gotenks circled earth 9 times, but but in the anime this light speed feat was slowed but to be fair if things were shown realistically we wouldn't see anything as fight speed exceeded human eyesight when Goku and Tien fought. Db not overwanked and all the planetary tall is true as durability and offensive capability is linked. Ex.Vegeta throws planet destroying attack and Frieza defects with foot. Melee attacks are in a sense planetery when they can hurt someone with plantery durability like frieza it simply doesn't destroy the planet cause the attack is condensed and lacks area of effect, same with none explosive small ki attacks.
Dbz durability seems lacking when it comes to cutting type attacks...look back at Krillen vs nappa when vegeta warned him not to take the attack.
Db part had gag stuff that couldn't be taken seriously...Krillen no nose joke/Later krillen smelling things as if he had a nose.
Piccolo never called his attack light-speed in the fight against Raditz
The much hyped Namek battles...take into account that a normal human like Bulma wasn't bothered by the planets gravity so it couldn't be much different than earth's. Look at how long it took them to fly from place to place. One feat people hype is Goku crossing namek after arriving...but if you read the manga...you realize he arrived really close to the place he flew to.
Faster that eye can see<Light speed
Planet bust=Core bust
Gotenks Panel=No time-frame
How the z warriors thought it was impossible for Goku to go to kami house and back when he was demonstrating Instant transmission...that would be nothing for people who really were light-speed.
The cell thing was dumb...Goku blows of cell's entire upper body- he regens. Cell suicide bombs-but survives due to an undamaged thing that was in his head?
How quickly they tire after throwing out a few non planet busting attacks. Their energy drains quickly when they get hurt.
The Manga really de-hypes them to be honest:yeah:
Also Goku vs Beerus fight really crapped on their speed...comparing their movement to the splashing water.
