This kind of logic is why I became completely disenchanted with DC, and to a smaller degree Marvel, around 2005. When I realized that the JSA had three geniuses on their team (Mr. Terrific, Hawkman, and Mid-Nite), access to nano-tech (T-mask) and Ted Knight's tech (Cosmic Rod), yet their best defense against most threats was "let's hit them," I realized they were grade-A fucktards.
I like Guardians of the Galaxy, though. No slouches there when it comes to applied super-tech. Bue Earth heroes, not so much.
