If you tap it, the animation is a lot tighter and faster, giving you less evasion frames but making it faster/harder to dodge.
When holding it for a second, go get more evasion frames but it’s more telegraphed (like it is now). This would add fun (IMO) and versatility.
Not sure if that’s possible with this games mechanic’s/engine or whatever (not a tech guy) but I would love this change.
