They actually do. The Champion Shell comes with all the current upgrades for the base unit and you can eventually upgrade the base units to have that ability too. Talis already has the projection shade ability even without the research, Mojo I believe already has the range of an upgraded scout but gains even more range when upgraded. Warbringer already has the +2 range upgrade, and Clolarion already launches interceptors at a faster rate. If you gave the base units the abilities of the champion ais, even if they were weaker, would make his army even more OP than it is and essentially rob the Champions of their purpose and also render Tactical Data Web and Avenging Protocol near useless.
