There I'd agree with you. I think if a big storyline centers around a certain character, then it should feature THAT character and those associated with him/her, not a whole bunch of other characters. If you want a great big crossover event that features characters from across the DCU, then write something involving the JLA or JSA - team books can get away with that sort of thing, because it's inherent in their structure, anyway. A book featuring one main hero, however, should stay in that hero's world - otherwise, the concept is diluted, and the story lacks punch.
