As for why Susano'o... well, he's typically portrayed in media as the "bad sibling" of the trio, since his domain is storms and he's kind of a jackass. Got kicked out of Heaven for it.
Yeah his general tendency to wreck stuff does make him the perfect god to call upon to give the people threatening you a really bad day. Honestly, I'm more eager to interact with the Kjoin than their primal (not to say I'm not psyched about him to).
