You know, I've been thinking and when Capcom releases the SE version of DMC4 they should make a few changes to Dante's set up. I think they should have an equip option and let the player select their weapons and their order for them. If a player wants they can equip no weapons and bare knuckle it (like when Dante can pound enemies mid sword throw), or they can just equip one weapon set (gun and sword) and it can be like DMC1, or 2 sets and be like DMC3, or all of them and be like DMC4, or any weird combination. This allows those who maybe don't like a certain weapon to avoid having to use it in the rotation. It would also be nice to choose the rotation as well, though it only really matters when all the weapons are equipped. In addition, I think we should be able to assign a style to each weapon, that way we don't have to run to the d-pad each time you want switch style, so for instance I have a tendency to use swordsmaster when using Rebellion, if I equip the style to rebellion I can automatically switch to Rebellion and swordsmaster in one go from whatever I was in, allowing for combos to flow a little more naturally, as I feel going to the d-pad breaks things up a tad too much. Of course, this could be bogged down with styles switching every weapon making the game unplayable, so we need to add another option, "default." Now, what default will do is it will carry over whatever previous style you were using, thus you can plan out strategies and combinations that suit your tastes best, so for instance I could set Pandora to gunslinger and the rest of the guns to default, have Rebellion with swords master, Lucifer with trickster, and the rest on default, as such every time I switch into a weapon I have a style preference with it'll be there, but if I switch to one I don't it'll just pick up where I left off keeping thing a bit more in control. Of course, this raise a bit of a problem in reference to Yamatou, but perhaps Capcom can decouple things? Oh, and of course the d-pad style switching will still exist as an override, and you can maintain the exact same dynamic as 4 has now simply by setting every weapon to default. Oh, and an in game equip option will be needed to be added, naturally. I think something like that could lead to a natural player specific combo set up... tapping the d-pad constantly feels a bit awkward, IMO, and I feel this would alleviate that. If nothing, players could just set everything to default and ignore it, and I agree it's a bit redundant in some cases (only using a single weapon set, for instance), but it offers up more choice and combat customization, so it's not like it will hurt.
Also, sorry for the block of text.
