I´m new player and i see Youtube videos where people change fast weapons to do more dmg.
I have a 4 star gear (chaos set) and i try to do the same and i cant.

The rotation shot, shield, switch 2-1 weapon and shot.
The problem is with shield.

I have to press only a moment or i have to wait a few to cancel action?

Beacause if i press shield fast after shot, the shield doesnt work.

Sorry for my english.
