hmmm....seems to be fair enough but atleast when i dodge backward it shouldnt work on me. But sometimes i have experienced situatoins where i dodged and peecekeeper;s GB didnt get me. Im not sure if this has happned with other chars. So sometimes it doesnt work. still, I think GB should works only on characters that are not in dodge state. you cant dodge all the time so GB has a chance to be done when player is a state between dodges.
Sorry fro my gramma. I hope you understand what I want to say ^^.
