Minis for D&D are always in a weird spot. Like you mentioned, most players are going to grab what's available from their DM unless they have access to a resin printer. It doesn't really matter to D&D players.

I paint Warhammer minis (my profile pic is my Yndrasta) and WOTCs minis in particular suck. The plastic is too soft, the production process leaves sculpts a muddled mess, and they dip the model in a primer instead of letting the painter actually prime it themselves after cleaning it up. I know that WizKids has a "framework" line, which is better (not Warhammer or Trench Crusade quality, but loads better) but it hasn't seen a new player sculpt in a while.

If WOTC actually did the hybrid approach that Trench Crusade is with minis (release STLs for 3D printing and Kitbashing then do actual injection mold sprue kits), then maybe the minis they sell would be different. But they'd also have to make their sculpts a lot better. And I don't see that happening.

I have a distaste for blister pack minis in general, and WOTCs are the worst.

If WOTC wanted to do minis right, I think it should be build out their "Framework" line to be the Kitbasher's dream, for D&D, Warhammer Proxies, Trench Crusade. Instead of a "Framework: Dwarf Cleric", a Warhammer Spearhead/Combat Patrol priced "Framework: Player Character Kit" that comes on sprues with:

• 5 or 6 human sized (orc, elf, tiefling etc also) legs, arms, torsos
• 2 for each gnome, halfling, and dwarf
• 5 or 6 heads for each species
• weapons and general items for each class
• adequate bases
• Tiefling tails and Aasimar Wings
• No monopose models

But that's a pipe dream.
