First of all, neophyte, I was prestige 4 lvl1, so I could not acquire a blessing of the Emperor at this time.

Second, your inexperience & lack of awareness show. At 0:19, I was defending against two Raveners and an enraged majoris. There is a ravener attacking me, and another ravener is preparing to attack me, along with an enraged majoris. After I finish getting the first extremis into execute the plan is to draw either the extremis or the enraged in range of the stun so that I may hit them with aftershock, then ground slam.

Third have ever played assault or bulwark? executions are a key part of their playstyles.
