It definitely needs some balancing; I keep losing to a level 4 who is active when I am not active and I think it should still be somewhat difficult/rare for someone that many level down to be able to win every time just because they are active. But, I think the dev's are really trying to dirve the idea that combat is tied to your activeness on steemit, which I am okay with....but I still think a little balancing is in order :)
