Ehhhh I can see why some people might think this way. Although I dont agree. Dragon ball definitely has a story, and its pretty good. The story itself can be basic at times, but the characters driving the story are what makes it special and interesting. Theres a ton of character growth and cool shit happening all the time in the story that even though it usually boils down to Villain wants to take over or destroy the world, its interesting to watch because the villains are developed so well, much like the cast of heroes are. Lacking strategy in the fights is true for some fights, false for others. I do wish we got to see more high fighting IQ in Dragonball, but many fights still incorporate strategy. Gokus use of Kaio-Ken, Solar Flare, kamehameha trap under water, instant transmission kamehameha, just as some examples. However, compared to something like say Jujutsu Kaisen, the strategy in dragonball fights are relatively basic. Theres definitely some just straight up slug fests in dragon ball too, and there are other mangas/anime where there is a much higher emphasis on fighting strategy.
