I am currently playing Scrapper. Sometimes when I'm in a fight in WvW, I am unable to stomp a downed player. Instead of having the option to finish an opponent, I get something called Gyro Smash. It messes up my WvW fights, because I am unable to stomp enemies when my gyro is on cool down. It is not always possible to simply cleave my downed opponents. I did take screenshots of this issue. However, I have no idea how to post screenshots on the forums.
