Just because a combined nature's component is weak against another nature, that doesn't mean the entire combined nature is. Case in point, Haku's Ice Release. Sasuke used fire against it, and despite it having wind chakra, it did virtually nothing to it. to be fair, they showed several tims in the story that the "weaker" element can overcome the "stronger" element if it is high enough,

hakus ice was simply on a different lvl than sasukes fire, this could also be the reason ^_^
