I'm an avid miniature painter. I love to paint them. So, I usually paint my own. I prefer the sculpts and designs of other companies (like Reaper Minis) over the WotC ones.
That being said, with little free time I have, painting tons of miniatures so I have a representation for everything is next to impossible. So usually, with my groups, we have nicely painted minis for the Players....and counters, dice, glass beads, etc, etc for everything else.
Quite frankly the WotC minis are poorly painted. But hey, they're mass produced! There's no way to make 'em look awesome in an affordable manner. But.....next to dice or pieces of paper, they look beautiful! Ha ha ha. Anyways, what I'm saying is this....they do a pretty decent job of being battle representatives on the map. It is a shame that we can't just go out and buy what we want. It would be so nice to go to a local hobby store or something and just buy 12 orcs.
Well, a previous poster brought up a good point saying that collectors would present a problem. They would make your trip to pick up 12 orcs miserable by going to the store and picking them up first before you. I'm not a business major or anything, but I thought it would be nice if they were sold in stores like toys (you buy what you see) and if the store didn't have it, you could mail order specifics through the retailer or something.
Oh well. Too bad......
For now....I don't buy 'em. Just too much trouble. I search for minis that match the character descriptions of the players (by looking at the shelf of the local hobby store - - if it ain't there on the shelf, then its not being bought by me), purchase what I find , paint them, and everything else we make paper counters or use colored dice (example: red 6-sided are orcs, the orange ten-sided is the Orc Chieftan.....)
