Well, from my point of view. (I did quite PvMP back in the old day, before Moria) The most needed it's both Freep and Creep. But Freep and Creep who wants to play, not spending their time waiting the other camp to be in inferiority in order to crush them easily.
This is why I quit PvMP, tired of waiting for a fight just because the other camp got some people more. If you could change that, you're a wizard
