Why is heavy storm banned.?

a really good card that helps a lot. i know malevolent catastrophe is ok but only if they attack. in my opinion there's a limited use for malevolent catastrophe. not all players will depend on attacking to win. exodia and burn decks are a good example of this. ive played yugioh for years now and the thought of heavy storm staying on the ban list really sucks. i dont see how its broken. your opponent should play all his spell and trap face down knowing there might be a heavy storm coming ttheir way. skilled players only play whats necessary and not all their spell and trap cards when they draw them in my opinion. now that heavy storm gone from tournament play, people can now lay down as many as they wish without much concern. mst and dust tornado is ok too but often players will have more traps and spells then the limit on mst and dust tornado. i dont know why they banned heavy storm. it was a good card for every deck.
