I had a similar feeling about a year ago. I had pretty much full sets of all the MU waves on card, neatly displayed. It looked great but felt empty. That big pile of toys stuck in their boxes seemed like a hollow victory.
To me you sound like a guy that is into the hunt, not the kill, if you catch my drift.
I was the same and then I turned it around. The planet hulk wave turned up along with Galactus and I lost my mind. I spent a weekend tearing through the packaging and liberating every single figure I had. That was when I got my mojo back, having all those guys out, en masse, ready for posing and display won me back.
Now I can't wait to get the toys, not for the sake of having them, but for the sake of fitting them into the display.
You got to get hands on with these things, otherwise they might as well be in a vault.
