No, it doesn't. Like I said earlier I usually do my main models in the spline modeler. Which is pretty to get symmetry in. If I need to I convert it to the vertex modeler and go from there. This process is much faster and less mouse intensive than just using the vertex room for a lot of things. You just have to be good at figuring out how the object will look when done. For instance the wings on my Raptor fighter are actually one symmetrical model, done in the spline room. I have yet to find something which cannot be done this way. For people I just use Poser, so no it doesn't bother me much. The whole symmetry thing has been rehashed to death so Im not going to comment on it further.
