Just tested it yesterday with raidbot and lazyraider and it seems that its the raidbot is causing the lag bcs on ultraxion and madness it didn't lag with lazyraideer at all. Clicking the aoe option on/off doesn't help
HS with 2 piece T13 doesn't have nothing special "rotation" instead i would rather fallow
Use Heroic Strike whenever you have a Battle Trance proc or you are unable to avoid being at maximum rage.(So if over 75 rage)
Opening Rotation
Battle/Commanding Shout + Charge + Berserker Rage
Rend
Colossus Smash + Heroic Strike
Deadly Calm + Mortal Strike
Continue Single-target Rotation*
Deadly Calm wears off -> Inner Rage (if you have the 2-piece)
+ Recklessness (try to time these during a Colossus Smash)
Begin Recklessness Rotation
*
Single-target Rotation
Mortal Strike
Colossus Smash
Overpower
Slam during cooldowns
The use of Recklessness along with Inner Rage will cause you to literally explode on damage output. Due to the fact that you'd be near maximum rage during Recklessness and Inner Rage because of Deadly Calm, you'd be able to throw out cheap Heroic Strikes that are almost guaranteed to be criticals. A massive string of critical hits right near the beginning of the encounter will surely put you in at a great start.
Recklessness Rotation
The Recklessness rotation is almost identical to the standard single-rotation described above with a few changes.Overpower is now used in conjunction with Heroic Strike (even better when used with Inner Rage as well) when rage permits and Slam is still used when Mortal Strike, Colossus Smash, and Overpower are on cooldown. You may think that using Overpower during Recklessness is a waste of a potential critical strike on a Slam instead, but using Overpower and Heroic Strike are mathematically superior to a single Slam.
This is a slightly more advanced opening rotation one could use to pump out absurd amounts of dps during the initial engagement of the encounter. The difference here is the use of Deadly Calm's ability to make none of your moves cost any rage and Inner Rage to reduce the rage cost of Heroic Strike should you have the 2-piece bonus. This is why after the Rend, you immediately proceed to dump as much rage as you possibly can through Colossus Smash and Heroic Strike. As soon as you come off the global cooldown, pop Deadly Calm which would allow you to cast Mortal Strike and continue on with the single-target rotation. When your Deadly Calm buff wears off, you'd likely be at near maxed out rage, which is why Inner Rage is used directly afterwards along with the t13 2-piece bonus to throw out cheap Heroic Strikes while maintaining a decent rage pool. Should you have executed this correctly, your damage output right off the bat would be outstanding. However, another addition can be made to the opening rotation to cause even more major damage: Recklessness.
Probably there are ppl that know a bit more eon warriors so this might not be 100% accurate but that't how i done it before manually.
