All Rounded MMA?

I was just reading U8Dust's post "Most Well Rounded MMA school", and
it got me thinking. Wanderlei, Rampage, Couture, Sak (In his prime)
and a few other people seem like complete package fighters. Is Pro
MMA complete yet? Eddie Bravo I think said something like "MMA
Without submission is just bad kickboxing." What do you guys think
needs to happen so that MMA has more complete fighters. Is MMA
going through a subtler thing it was going though when the UFC
started, when it was prodominantly about weeding out the effective
from the inneffective? I feel like I may have not asked the most
cohesive question, but I think you get the gist. Let me know.
