Quote from user-12976315 »Dude, this is not a card created for be tournament viable in Storm, in fact no serious modern or legacy deck would ever play that card, because it's completely useless for the archetype, it costs too much and it does nothing on it's own. When I talk about supporting storm I'm talking about more aggressive and cheaper rituals, cantrips or the actually storm mechanics, not overcosted junk that could see real play only in casual games inside casual strategies.
I myself wouldn't mind if Grapeshot would cost 15 mana instead of 2. At least wouldn't be tournament viable.
Oh yeah about that : Seething Song another card banned exactly because it was played only in Storm and make it too good.
Counterpoint: they banned ~8 cards in modern mostly because of storm but made sure to never ban the actual storm cards.
Someone somewhere at WotC clearly thinks that it is a deck worth preserving.
Which imo speaks against your "WotC thinks storm is unhealty and unfun" narrative.
