The group i'm in currently is 1/7H in FL and working on Ryholith. We have tried many many different things on this fight but we still arent hitting superheated before he transitions to phase 2. We attempted to 2 heal it and the problem we encountered was with the additional DPS we were much closer to pushing him but everytime players switched from sparks/fragments to the legs to dps him some, they ended up making him wildly turn, miss volcanos and ultimately wipe us since it is very unforgiving with only two healers. When the steering gets messed up like that and assuming we can recover then he's already walked over a ton of obsidian and gained a tone of stacks back. We currently steer him into volcanos until the 3rd spark dies then the other dps kiill fragments and neglect the 4th spark. This is usually around 4:15ish and we lust soon after to try and push rhyolith. He is almost always at around 40% with anywhere from 10-20 stacks of armor which seems to me to be in excess depending on our RNG.
I think our dps needs to be higher or at least go with the 2 healing which we could manage push him into phase two before the superheated starts to stack providing we have good RNG. Our Comp is as follows:
Tank : Pally Tank
Healers : Pally, Disc priest, Druid (or our 7th DPS as balance)
Steering DPS : Feral Kitty, Enhance Shammy, Frost DK
Spark/Fragment DPS : Fire Mage, Demo Lock and Hunter
The problem with steering comes when the spark/fragments are dead. Anytime the dps on those things switch to the legs he starts to turn out of control. I'm not sure if I should simply be expecting more RA about the turning mechanic or if i should consider the 2healing with the additional DPS focusing on the legs as well. That'd be 4 turning and dpsing him overall at all times. The addition of the boomkin makes it nice to be able to blast the adds back but im not sure how effective he is with it honestly. I've asked everyone to double dot both legs to squeeze as much DPS out as possible since it doesn't seem to affect steering too terribly but its less stable that way with 2 healers. Everything must be done perfectly no damage from stupid stuff.
Thoughts or tips? I'm open for any ideas on how to work this. Im thinking for the evening i'll have us 2 heal and test the 4 people "steering" but consistently dpsing Ryho and see how that works. Any help is much appreciated. Thanks!!!
