I'm proposing a rule of completion: when a new keyword is introduced, there should be enough figures in the set that possess the keyword to run a 300 point team.
Web of Spider-Man gave players a complete set of U-Foes, a playable force of Dark Avengers, a H.A.M.M.E.R. army, and while it wasn't "new" the Outlaws were rounded out with 6 new members (adding to the initial 2) capable of making 300 point modern age teams.
First Rule Violation: It's understandable that Game Design couldn't fit every member of M.O.D.O.K.'s 11 into the set, and while the 4 teammates that appear are welcome, they only total 233 points. Another ~ 67 point figure would have been welcome, and helped reach that 300 point goal. As it is, fans are left waiting (and hoping) for the next set to round out the team with other members like Armadillo, or Mentallo.
Second Violation: Perhaps an even bigger insult is the Marvel Divas, a four person team of grrrrl power, hailing from the 2009 mini-series by Roberto Aguirre-Sacas. WoS included Firestar and Black Cat, leaving out Patsy Walker (Hellcat) and whatever name Monica Rambeau is calling herself these days (Photon? Pulsar? Captain Marvel?).
While my wife nor I didn't care for the mini-series (the characters never felt honest, I suspect because it wasn't written by a woman) I do enjoy the four leads visual appeal (Ginger, Platinum, Brunette) and would like to field them on a HeroClix map. Others hoping to play a Modern Age line-up of Marvel's riff on Sex and the City (and Birds of Prey) will have to wait.
Hopefully, fans will not only see the theme team completed in the next Marvel set, but the Divas will also total an even 300. Currently the girls add up to 133 points, leaving room for a 60-70 point Hellcat, and a 90-100 point "Ms. Phot-ul-vel." As it is, comic accurate 'Clixers can field the fab four using older Golden Age version, but at best the team adds up to 275 points - far shy of that round 300.
Asking for Keyword Completion on the Divas is not asking a lot - their series spanned four issues, and ended. Web of Spider-Man had room to squeeze those last two Divas in. Instead, fans are left waiting, and hoping that the figures get remade, and not sent to limbo with the Morlocks and Serpent Society members.
