Guard Readiness - reduce damage, helps generate more aggro, allows to use some abilities like Incitement
Incitement - you should see 8 second cool down on this. Please check if cooldown works
Brazen Feint - This is kind of emergency Incitement when you Incitement on cooldown or Fighter is silenced (silenced fighter can't use Incitement). Brazen Feint forces mob to attack you for 5-7 second and do damage. So this is like free hit but it does not increase aggro towards tank so after effect wears of (and tank did not get aggro other way during effect) the mob switch bad to attacking previous target.
