Because we're not hardcore enough.
I guess when you have threads and users here advocating about removing Dante's Style System and having a dedicated dodge button you probably aren't hardcore enough.
But things that I didn't know before listening to this video.
1. Sprint won't stop when you change directions. Basically Sprint will only stop when you stop moving the stick. Another improvement over DMC4
2. Goliath is more aggressive than Berial
3. Using Upper Battery in mid air in an enemy above Nero, Nero gains some more air almost like another jump
4. Petal Ray is also more effective in corners (even in large areas) and apparently consistent
5. The mosquito demons might be able to drain your health and give it to other enemies but if you kill the mosquito enemy they drop health orbs
6. Not everything can be parried with Battery. Battery can only parry physical attacks
7. Gerbera's Jocky can parry projectiles. Jocky only has i frames in the beginning. If you're not careful you can get punished quite easily.
8. Double Down (EX Split) can knock an enemy up or knock them away based on position
9. During Stamen Ray Nero can't turn 180 degree and can be injured while using it if attacked by behind according to R K.
