See one of my favorite things that Armada did was standardize the holes in the hands so every weapon could be swaped out. With the movie that kinda went by the way side, but in turn hands have been getting more detailed with fingers, and thats cool too.
Still if a bot does have a fist hand, with a weapon hole, I think it should have a standard size port. In reguards to this and figures with smaller hands, I give you the Armada Seekers. Those hands may have well just been rings!?!
Now I know the ongoing argument that Hasbro wont make add on accessory packs cause they wont sell.
My solution to that, make them Robot Point mail in extras
Not only will that make the fans happy, but it would increase sales because
A) people will buy figured just to get some extra points for the kick ass mail away parts that they otherwise couldn't get
B) people will buy more bots cause realy, do you wanna save an imperfect box. Wont it drive you mad knowing that the box you would normaly save is now flawed...
C) I know it will so more bots will be bought for mint sake.
There is a bright side though to the profeteering besides mail away stuff. If we're prompted to buy more bots, that means there will be less surplus for repaints, hence newer molds sooner
But you know what, it's a win win for everyone that would make us happy so they'll never do it.
