There's a reason there's only one Avatar in the Avatar series. Bionicle could do without having six of them. I mean, I miss the mask packs too, but giving each Toa control over all six elements would be a bad way to go about it. When you put it that way I guess it makes sense, hehe In that case, maybe the golden masks are just power boosters? Like, Avatar State but with only one element Kopaka standing before an avalanche like, "Master State, yip yip!"
