Many great ideas!
But the next weapon's pack will only be a repaint of the already released weapons.
maybe that will change in the 3.0 weapons pack... I hope so because indeed many of the packs you mention would be good to see in the line!
But If I would have to choose between new tooling for a pack or for a figure I would chose the new tooling for the figure.
The budget of the MOTUC is limited... fans have to make choises.
About that, I would be really interested to know how the budget of the MOTUC line has evolved since the begeining... +200% ?
