I do the opposite. I collect everything but the keys because I can't afford the damn things.
I hate that the movies are making the keys multiply.
I used not to pay much attention to the so-called "keys" when I started. In fact, I went for my favorite issues, and when they happened to be "keys" I was annoyed because they were excessively costly. So, for example, I picked a #36 but skipped the #48 and only bought lowgrade copies of #49 and #50.
Since when I restarted, obviously this "key frenzy" which is mostly artificially driven by hollow speculation bubbles has influenced me, but I always try to go for the issues I consider more meaningful, or that are considered best stories and/or more importants when I am not a "completist" (like I am with FF, Defenders and Dr. Strange).
That’s what I do with most of the other Marvel titles, anyway. I have little to nothing of Atlas, but recently picked a Black Knight #1 (sorry, *Bronze_age_fan*… ).
