Alright so this statement always annoys me. Power Levels are not bullshit. The only reason why Toriyama removed them were not because they were useless, but that it would spoil the fight. For example, if person a has a power level of 10,000 and the person b has a level of 8,000, everyone who's reading the Manga or watching the Anime would know. If you want proof that Toriyama didn't say Power Levels are Bullshit then here's a link. This is officially translated by the people over at Kanzenshuu who are experts in Japanese.
