I thought the BAF concept should have been killed years ago. Once they stopped shipping full cases so that places like Target, Amazon etc. could buy solid cases to make it easier to fulfill online shopping orders. Once that happened, I hate to think about how much excess plastic was used for BAF parts that could never contribute to a completed BAF.
Themed BAF waves in the early days of the line made sense when almost all characters were newly made - and at worst B listers - and the characters were connected. Un-themed waves never made sense to me. The mixed comic and film waves never made sense to me. Too many times Hasbro seemed like they were trying to retrofit a wave with comic and MCU just to comply with the BAF concept, or with a hodge-podge of characters for the same reason.
I would argue at this point that the BAF is no longer making figures we wouldn't get otherwise, given the current options of deluxe figures, made to order, etc. Maybe in some rare cases, but not often. Because to me the logic is:
1 - If the BAF is popular enough to get people to buy figures they don't want otherwise then the BAF would have sold as a stand alone deluxe release.
2 - If the BAF could not have sold as a stand alone deluxe release, then it isn't popular enough to get people to buy figures they don't want otherwise.
I am grudgingly buying some figures to get Skurge, but I'd be much happier - and I honestly think it would sell more - if this was an all Thor wave.
