How would that be considered an exploit?? sorry but lol...
There's lots of attacks, from various bosses and mobs, that work the same way.
So are they gonna ban everyone that ever evaded Thunder attack, from Succubi, also??
Exploit would be to prevent Rafflesia from even using devour. Dodging a skill that has a delay, isn't...
There's rarely only one method to kill a boss; just cause brambles prevent being devoured/stunned, doesn't mean it's the only way to do it.
