^ A good Morde doesn't merely use E to harass, but to build shield up too. If that miss, then just activate Q or W instantly and use it to return harass if Kassadin got near. Otherwise, Kassadin shouldn't have even enough damage to break shield and damage you at the same time, during the laning phase.
