I'm a little shocked at all the complaining about the BAF figures. If Star Wars had something where you get a free tauntaun or wampa part when you buy each figure, I would be all over that.
Obviously the strategy is to get you to buy everything in the wave to build the BAF. If there's stuff you wouldn't normally have bought, but you did to get the BAF, then their marketing dept. is doing their job.

This is no different than having to buy one of each vintage style SW figure to get your mail-away Lucas is it?
And yet people whine that they have to get a few extra figs for the BAF. You know, Hasbro could just stop putting BAF parts in with the reg figs. They'd charge the same price, you'd still get the figures you want, but instead of having a chance to build a BAF you'd have nothing extra. Then they could make Blob a Target exclusive and charge you $25 for him. Orrrr, you could just spend a few extra bucks to get the couple of figures you really don't want, use them to make Blob, and get rid of the extra figures on here or Ebay or use them for customs or whatever.
