I don't play Standard, and I quit playing modern last summer. I've played Magic since 1994, when I was 11. And I've played competitively since I was 15, so 1998. I've played Modern since the format began.
I follow Standard. I watch every pro-tour on twitch, look through the top deck lists at every Starcity and GP tournament each week to see what is going on. The pulse of Standard affects Magic a lot. I'm big into Finance. I trade professionally for a living (Stocks, Futures, Options). So trading and speculating on Magic comes naturally to me, in line with what I do professionally.
I don't have the time to invest into playing Standard/Modern competitively anymore. I'll always play Vintage, and I'll play Legacy because it's a way to play Competitive Magic on my on time frame....not having to keep up with rotating sets and new cards changing the format.
So, while I don't play these format, I have seen every iteration of Standard and Modern since their inceptions. I know how the game works, cyclically that is, with Finance and Player Growth. That's why I am worried about this stuff happening in these formats. It's one thing when Standard is bad (say Invasion though Odyssey block) and another thing entirely when it becomes Mirrodin.
When Wizards first printed Mythics, they promised the player base they wouldn't need those cards to compete in Standard. While that was clearly a lie, there is a huge difference between needing them to play the most competitive deck, and needing them to play the only competitive deck. When you have to buy $50 Saheeli Rai's to play in a local PPTQ, knowing full well they will get banned and go to a much lower price, you are whipsawing your customers and that creates a bad feedback loop. Some people won't care, heck some will embrace the game being about how much their annual income determines the win/loss% in standard, but the vast majority of players will bitch and moan and finally walk away from the format.
And that is what I care about. I don't care about playing Standard, that doesn't effect me. I care about the growth of the player base and new players liking Standard. That's what impacts the Vintage community on a large time frame.
