This looks really fun! It looks like (and as you said earlier amo) my shield (60% increase run speed) might be very valuable from Ishamail and me.

The aoe damage spikes are quite hard but also seems the only danger in this fight healingwise.

For me anyway I need a couple of more tries to get a better understanding of the damage output, but every thing we can do to lessen damage is needed.

Its very easy in this fight to think "im just gonna get this spell off before i move from that sonic circle coming towards me". (very bad thing to do though)

We have 10 gongs, they say that its quite much and we shouldnt be afraid to use them.

Aoe really seems to be the main problem for me too, not so much the tank healing as it seems to work well enough for me to throw a few greater heals/renew when tank is struggling to keep up.
As you are saying Trizz, having the time to cast heals is an issue thats very hard to deal with. As for my spec the -15% mana decrease on instant cast heals seemed pretty good, as I need to keep up Circle of Healnig and Prayer of Mending throughout the whole fight.

Two things I figured out that ended up being very helpful for me towards the end of the evening:
1: On ground phase, when sound-discs come towards where I'm standing in the middle (as ranged), I find it better to do a right-turn if possible so that if I'm targeted with "following flame attack" I don't end up running through the whole raidgroup, potentially killing off people. Also, if we do this well together I don't need to worry so much about being in range to cast body and soul (shield+60% speed increase) on others.
2: Think of the sound-discs as a bit larger than they are. Even when I just dodged them, in my mind perfectly, I still got the damage and sound increase.

I said these in chat last night but I figure it might be helpful for others who werent there/didnt see it.

From my perspective we're doing very well considering the few tries we had!
