The gravity of said changes? I dunno. The most obvious would be making the higher tier FFs much, much more expensive which I'm pretty sure would happen even without a pandemic, lol. And of course I'm assuming lower tiers will have certain dates cut off (like Sundays, i.e.). But as
@Brian G. said, too early to tell. I'm cautiously optimistic since supposedly we're getting vaccinated by May, but who knows?
