Okay, now I have something to try to mimic in DmC to see if I can address the feel or impact you're going for. I will say you're forgetting that you can cancel glide at anytime into angel dodge and its a double tap really fast, as for getting to your enemy, and picking the right one, I doubt even while using trickster you really can pin point the enemy you want and keep the speed momentum you seem to be craving that dmc3 trickster is providing. IN those videos, at best isn't the player (you?) t just pressing enemy toggle and the trickster trick up move towards the enemy they want. You can do the same thing in DmC without lock on, well you can't literally trick up, well Vergil in DmC can, but with Dante, all you have to do is point towards the enemy you want to rapidly move towards and use Calibur, which is as simple as pressing B with angel trigger held. Once you calibur towards an enemy you can cancel it as you're about to reach them, etc, or you can angel dodge to someone else. All of the aquilas skills can be cancelled at any point in the frame with an angel dodge.
Couple other things, roll dodge can't really considered a move now can it, we have dodge in DmC and I think its much more fun and reasonable to map it to a single button. Now you just point and dodge in any direction you want, and I believe Dante rolls in that direction.
As for the Royal Guard cancel, I believe I know what you're talking about, I've seen it in some expert DMC4 videos, however, I still think Royal Guard is overrated, because I doubt enough players used it. And DmC did bring it back, you can parry every attack in DmC, which negates all damage, and then coupled with Demon Dodge boost, you practically have no need for a mechanic like royal guard. and, honestly, does DmC dante even need another buff for parrying, he's already superman in the game in terms of power vs enemies.
