Was just a race against the enrage timer in all fairness, found myself wiping a few times to it so decided to try out frost, the phases were dealt with a lot quicker but the damage taken was too much too handle so I decided to go back to blood and give it my all, pots, drums ect.
Not really any major concerns, just had to time my AMS with breaths/sparks to get as much uptime on the boss as possible.
Hope you enjoy :)
