I get a lot of bugs on the fighter master's rage from players complaining that they used it thinking Creature X qualified for the mastery ability. Then when they realized it didnt work they had wasted a long reuse skill. Now all the mastery skills should gray out when not useable in gu47 which should make the fighter version more user friendly. It's a skill that low level newbies get so this is one of those cases where you want something that is easy to use and understand for them. It will go to test this week and you guys can try it out. It's nice damage and fast refresh with a nice debuff though so you should at least wait and see before jumping to conclusions.
