So to preface, in 5.4 we were a 25 man heroic raiding guild that raided 2 nights a week for 8 hours total a week. We killed 25 man Heroic Garrosh for the first time in early June, and have had some trouble repeating as we lost quality membership to fatigue, but have killed it around 10 times since. The issue we always had were as follows in order of frequency:
1. First phase transition missing interrupts. A ton of wipes to this, especially after we were "farming" it.
2. Lack of DPS for "phase three," being the part after he firsts hulks out and turns into super garrosh. We would hit an "enrage" of sorts being the empowered whirl when we had ran out of room to move him.
3. Mismanagement of positioning in the Stormwind phase, usually the Ironstar.
So this comes to the actual question and issue we had tonight:
We are about 20 percent behind in every phase from where we were in Heroic.
We had a third Farseer and set of adds come out in the first phase, and in the second phase instead of our normal 15~ percent push before the transition, we only had him at 35 percent!
We didn't have a lot of time on him, so didn't get to see much of the phases after the second transition, but as of right now it appears that even if we dropped another healer we aren't going to be anywhere close to where we were on Heroic. Our vocal core is even deliberating how to handle the red crane transition, as it appears we might have to.
I'd love to hear from some raiders who have killed this boss 30+ times and had no concerns with Garrosh if you guys had any issues. Regardless, any input is very much appreciated. Thanks in advance!
