I'm very sad to see DDM go. I loved seeing cool minis with all the hard work (painting) done for me. I loved seeing random dragons, elementals, goblins, etc.
I've purchased exactly 3 DDM products; the Gigantic Black Dragon, the Gigantic Blue Dragon, and the Colossal Red Dragon. Why only 3 purchases despite obviously liking the line of products: Random Packs. I will not purchase random items hoping to get the minis I want.
Here was what I secretly wished for: Essential X - Y Number of X minis
For example, Essential Elementals - 5 different Elemental minis.
Heck, I would have even shelled out cash for random minis if they were simply presented in theme packs (10 Random Goblins, 10 Random Elementals, 10 Elves, 10 Dwarves, 10 Abberations, etc). As a DM, I care that the goblin looks like a goblin, not that it has the exact color scheme and weapon I pictured.
WotC, because of their slavish devotion to producing DDM as a Magic the Gathering style game lost a chance to capture my money.
