I think the next step would be to utilize the down-on the d-pad. Allowing you to exchange between weapon sets. Each weapon sets with this control scheme can handle 8 weapons, so they can bring up the total to 16 all in one, 8 for set A, and 8 for set B logistical, simplified control scheme. Do it Ninja Theory. Fuck, use DMC3 weapons as pallete swaps. Cerberus could easily be considered an Angel, weapon, Agni and Rudra could be the Rebellion based universal weapon, and then you have Beowulf, Nevan etc. etc. All the work is done for you for a quick and easy patch update.
