Wow. Ok, first of all, with so many of you being old guard, might I suggest you take a look at the pre-modern format?
Premodern is a community-created constructed format consisting of the sets from Fourth Edition to Scourge. The card pool thus roughly spans the period inbetween the formats 93/94 and Modern.

(It looks interesting enough. I would get involved, but I own only a handful of cards older than kamigawa)
That ship has sailed with the MH series. A few of the mythics are more intended as staples that people need four of.
It depends highly on where you are. I live on the other end of NA. Back at the time where they were first available, I couldn't find Commander Legends, Time Spiral or even Jumpstart anywhere. And they were going as high as $250 or even $300 the box. And as far as shortages with AFR are, I've still yet to find any vendor asking over $140.
That's the fundamental difference. With this new Commander Legends set, I won't be able to find boxes anywhere. My only chance will be if my LGS gets allocated any of them (and they tend to get very little to none of non-standard releases). But if not -a very likely case- I won't be able to afford any, at least not for a very long time. (At least Commander legends seems to be back to a healthy $150 per box). Simply put, non-standard sets are very frustrating to meaningfully collect if you live south of the Bravo River.
