So we have spent some time on Iron Juggernaut last week and I feel like we aren't making any progress on the boss at all. The first night on attempts, we were destroyed in p2. The next night, I found out about the range strat for p2 where you get knocked back far away to avoid the barrages we we still can't get past p2. We just can't keep people topped for the pulses. So I don't know if we have the heals for this or if I should just try another HM and come back to this one. Any help would be welcomed.
Would not suggest trying another heroic boss, this is fairly simple and if you can manage the other bosses before this you will be fine.
You dont have a single paladin in on the attempt i looked at, what we generally do is AG the first knock back into the corner, then take a loose spread and use AM for the remaining 3 pulses along with Tide rotation, rarely have a problem with this.
Just try make sure you have a CD rotation of a mitigation CD and a healing CD.
CD's you could use: AM, Rallying Cry, Smoke bombs + Spirit Links, Feral Tranq's going INTO the shock pulse, Priest barrier.
Here is a link to our most recent kill,not our best healing setup, but if you use CD's correctly you should not have a problem.
PS: Just looking at it quickly your resto shamans are not using healing stream on CD, generally its a nice idea to do so or hold it for shock pulse and rotate, but they are barely being used.
