Personally, I think a properly smoked brisket tastes like beef, smoke, and then a salty/spice flavor from the bark. What is your brisket missing?
Saiko makes a very good point here. To me a brisket is not a particularly "strong" tasting cut of beef. Is it possible your expectation is a little high?
