Hello there. My 5/13 HC guild decided to tackle this boss, and we seem to have hit a brick wall. This may be the result of poor tactics execution, but the encounter itself seems to be unforgiving at best. I'll start with a WoL from our last night's runs: http://www.worldoflogs.com/reports/rt-rigpa42fu0cxav5g/
At this point, I don't think it is as much of a dps/healing problem. If we can do council HC without too much hassle, we should do this boss too imo, although I may be wrong. Anyway, we're using the lock portals tactic where our raiders place the ice beams between them. We also had several people clearing them with cinders, but I've read that cinders should be dispelled asap and we should scrap this tactic altogether. What do you think?
Another problem is the worms. At first, we tried dps-ing them down, but the head died slowly. Then we assigned only a few dps to them while CC-ing them to the best of our abilities, but even that didn't work out. Some people suggested to do 0 damage on the worms and have then CC-ed until a rampage, then clear them out. Is that a viable tactic?
As for the heroism, a good number of people recommend using it at the 5th head. We've only got there once, but that 4th head is just the roadblock for us. There's way too many adds stunning the people, and they can't make it to the stacking point in time.
Any sort of advice or tips are appreciated.
