I've seen videos of the dance but nothing that really fully broke it down or slowly enough for people to realise whats going on so I've made this.
Just for any melee/tank, or anyone in general really doing the dance on Will of The Emperor dodging the devastating combo to earn the opportunistic strike here's a few screenshots and a short video that's 50% of normal speed so you can get a decent idea of how the dance goes, I've done this to try help anyone that's struggling or anyone in LFR to cause wipes not to happen as often
I'll chuck up a minute long video next week of heroic dance, although its exactly the same just 10 swings not 5. It would've been up first but I haven't recorded any of our heroic kills yet and over the Christmas break it was easier to just kill it normal because of roster.
The whole combo consists of 5 strikes that can vary of 4 types of cleave attack.
From the screenshots you can see that during the combo there is a blue graphic on which side of the boss is going to be covered. Just position yourself so your not on the same side as the graphic.
From the boss PoV, the boss is swinging to his right side, so I just stand on the opposite side.
From the boss PoV, the boss is swinging to his left side, so I just stand on the opposite side.
This is the "trickier" of the cleave attacks from what many players seem to have given feedback about. This is a ground stomp that covers an area around the boss in a full circle for about 5-10 yards. You can faintly see a white graphic of where the AOE circle will spawn underneath the boss when he stomps down. Try to position yourself outside this circle, be careful not to go too far away as the boss will grip you back into the AOE.
This is the boss's frontal cleave. He has 2 blue graphics in front of him and lifts up his left leg slightly. Run through the boss and get behind him.
(Sorry this screenshot is from the side, my camera angle screwed up while moving.)
Hopefully if nothing else, it'll assist some players learning the encounter be it normal or LFR and cause a few less wipes along the way.
