Have you ever seen a sorc try solo cap a node and get the defender below 80%HP?
P.S.: I dont have a sorcerer myself.
In normal wzs yes a few and being successful too. It only takes longer as there is lack of burst in sage/sorc dps and because they have to play the kite and hide depending on who they are fighting. Or very very very rarely with luck and a well timed 8sec mezz.
