The reason this will not work, is because the noobs will get absolutely swamped by veteran melee'ers.
Many times I have been on duels or groupfight with one or two other players who were obviously new to the game and I just kill them 20 times in a row and they quit the game out of frustration because it's not fun when you lose 99 percent of the time.
We could make this work though, if we had a ranking system like CSGO, to put the noobs with the noobs, the average with the average, and the pros with the pros.
