I did not Spam the jump button. Its in the description. I actually leaned my thumb at a constant pace left and right, between the jump and special melee button. In DMC3, the enemies move quick before I can jump and aim my Killer Bee strike using Vergil in order to jump off them. Its just hard to hit because it requires precisely timed impact/contact, a smaller open window to jump back and repeat the process. The enemy A.I.'s (the grim reapers carrying a scythe and the mobile eyes with blue and red energy projectiles) move quick before my attack with the beowolf gauntlets can reach them, at times. Note I played Son of Sparda (hardest difficulty of demo) mode here in DmC, while comparing it to DMC3 SE's hard and very hard mode.
If this wasn't a DMC thread, your discription could easily be thought as "spamming in rhythm. "
Well actually killer bee/starfall cancel was quite spammish...but forget that. Those are only beginners steps.
In DmC you have to have a timing specific for each move since Osiris and arbiter has a bit of time "extending" their blades. If you get it right you can do it in rhythm as you please. If you don't get it right, you have zero damage and be a sitting duck to all the flying drones. It's quite fair.
And for your starfall combo...It's actually the easiest enemy step combo in DMC3 since you have the lock-on and it's super fast. You can't be serious...
If there is some reasons you fail in doing it, it must be...
1. They are in DT mode. (DmC only has SoS so I say comparing is unfair.)
2. You haven't blasted them in the air first.
3. Your enemy just developed cognitive powers.
And for the problems of your enemies...the reapers or seven hells are actually so slow that I can't find a reason why you are failing, but If you are referring to the
enigmas you are dealing with a enemy that sucks so bad that even top-players would like to skip fighting them as possible...their AI is not good, it's just their mechanics sucks terribly like
fallen and
dullahans.
