For example just giving Ganon some more room to breath and force a different approach or godforbid pressuring/annoying the opponent a little can go a long way in turning the situation around or creating an opening.
I can understand why most people are so perplexed by the idea of

using projetiles and dictating the pace and rhythm of a fight, but if you really think about it, isn't that how it should be? Think back to the games ( and most bossfight scenarios in general) Link is normally the one, who observes patterns of the boss and waits for a certain attack or weakspot/opportunity to strike, but in smash it's the complete opposite concerning the two! Quite ironic isn't it?
