These days I pretty much only use a Mel's ranger and stake out the middle ground mine. Killing opposing carriers is one of the most effective things you can do: if they don't have any carriers they can't score any points. And since the carriers are pretty much always moving, Mel's is a great choice. Sloth Hunter's is good for that reason as well, but I've found Keen's lower energy cost and recharge work out better, especially when there have been times where I haven't died for a while (had one match where I didn't die at all, and I don't even bring a self heal).
