stun knockbacks

is there a reason why on my melee character (that is already at a disadvantage becuase... melee in this game), stuns a rare and they take twenty steps back into narnia completely knocking them out of any setup i had going and now i have to redo it at the next planet over where they fell to when stunned? just curious if we can get someone on that to fix it. been an issue since day 1 annoyingly
