Reposting for new page in case people missed out on the TRUTH!
Stuff that DmC has introduced that might get introduced into DMC5 which would make it a better game:
*Better Style gauge ranking system. DMC4's style ranking system is dated as fuck. DmC original Style ranking system was ass but the one in DE is super legit, easily the best one in the series. Itsuno would be wise to cop that shit and make some tweaks accordingly (it still rewards high damage on crowds too much but so does DMC4 to be honest).
*Being able to do Secret missions from the main menu. A god send. No longer do you have to go through an entire level and search for a secret mission to attempt it again.
*A training mode. It's bare bones as fuck but it's infinitely better than not having one at all.
*Lock on toggle option. Should be a mandatory feature going forward.
*A Devil Bringer that you can manually command whether you want it to pull enemies or make you traverse towards enemies. It's not nearly as fluid as Nero's Devil Bringer but I like the versatility of it in DmC.
*Being able to try out moves in the shop before purchasing. Also no escalation of prices on moves and every move costs the same to buy.
*Toggleable modifiers are available in the Mission select screen and not tucked away in the Options/systems menu.
*No Automatic mode. I have no idea why this mode is allowed to exist in a DMC game. It should never be in a DMC game again. Just make the easiest mode in the game something that everyone can beat rather easily.
*Some combat mechanics like Vergil's teleport cancels and Perfect slice mechanics.
*The Doppelganger system in DmC. DmC Vergil is something that is similar to DMC4 Dante tier in terms of ridiculously high cap potentially and that's due to the Doppelganger system. Unfortunately, DmC as a game is not going to survive for nearly a decade in terms of high level play and thus a brilliant system like this is going to be lost to the action game world (or the full potential of it). My hope is that Itsuno puts it into DMC5 in some form so that the hardcore DMC players can push it to its limit.
*Super detailed stats tracking. There's actually a very in depth stat tracking system in DmC if anyone actually bothered to look. It records even very minute stuff like how many times you have landed attacks with certain weapons, your variance on mixing up moves, how many times you used enemy step, your kills against certain types of enemies (your deaths as well) etc. This is cool and I would like to see it return for DMC5.
*Removed puzzle solving and backtracking almost completely. Say whatever you want about the story, the characters, even the platforming... but as an action game DmC keeps the pace up because it doesn't bog down the campaign with shitty puzzles or unnecessary backtracking.
*Pause combos transfer in between weapons. Not a brand new mechanic for action games (Darksiders 2 did it first) but it would be new for the series and thus a welcome feature for DMC5.
This list is already way longer than all the "good" stuff that DMC2 brought in.
Say you have Combo II of Yamato and Combo II of Force Edge with Vergil in DMC4SE. When you do a Force Edge ground combo and then swap to Yamato, you have to start the combo from start with Yamato.
In DmC, when you are doing the starting combo with Yamato, then pause.. instead of going into the Combo II variant you can switch the weapon and when you do it during the pause, the follow up that will combo is the Combo II of Force Edge... you wouldn't have to start from the beginning of the combo to get the Combo II finisher with Force Edge.
This is what allows people to do stuff like Two hits with Rebellion then go immediately into Trinity Smash in DmC.
