As talented as Eddie was, I don’t think he would have become famous without Dave. Dave understood promotion and showmanship better. I think it’s unrealistic to think egos that big could stay together once success came. Dave wanted to take full advantage of 1984’s success. Being impatient he did Crazy From the Heat and the success from that made him create his own band which was great but doing that destroyed Van Halen. Sammy Hagar woul be a side note of the 70’s and 80’s if Dave didn’t Persue his own interests. There would be no Cabo Wabo because that started with Van Halen. So Dave made Sam by default.
