Does the Cruiserweight division need to exist?

I have been 'Stating this for Years', and as a point of interest here are the 12 Divisions I propose ...

S-HW - 225lbs plus, and 6- 5" plus, the Only Division with a height stipulation.

HW - 205 - 225 lbs.

CW - 191 - 205 lbs.

L-HW - 181 - 190 lbs. RJJ could have been a perfect L-HW

S-MW - 171 - 180 lbs. Calzaghe stll a S-MW without to much effort

MW - 161 - 170 lbs.

WW - 151 - 160 lbs. Hatton stll a welter without having to drop 30+ lbs.

J-WW - 141 - 150 lbs.

LW - 131 - 140 lbs.

FW - 121 - 130 lbs.

BW - 111 - 120 lbs.

FlyW - up to 110 lbs.
