Guild Wars 2

Was wondering if this could be changed to getting in and out of combat upon getting hit. Instead of hitting ..
If i am hitting something, and it doesn’thit me i should be able to retain my normal speed since nothing happened that would slow me down.
If i get hit i would sustain some form of damage and it would be logic being slowed down then.
Also maybe getting out of combat when hp is refilled.

Is this an option?

guess i’’ll bump for an answer..

but who am i kidding, noone checks the suggestion forum ^^
