Wouldn't the casual fan just not
watch, and it's not catering to them at all for that reason?
It's the least-watched time slot of them all no matter if you're a hardcore or casual fan. Why would this cater to the casual fan opposed to a hardcore fan? Because they wouldn't HAVE to take off because they don't have as big of a desire as you? That's your personal decision man, like your hands are tied.
You're prioritizing what's most important to you.
It's one series in the grand scheme of things that this will happen, and if you don't take off and your favorite team ends up moving on to the CS, there's a lot more baseball to play / taking a day (two, apparently
) days off wouldn't be worth it.
If you don't take off - and they lose the series - then you were justified in not taking off and actually saved yourself the time.
