first: thanks for your guide, Ammunae!
I want to share my raiding experiences too.
I went DS 25m HC as disc today. For the sake of getting used to our new stuff, we raided without the Power of the Aspects-Debuff. Which was kinda fun at bosses like Morshok (Tank takes 2 200k hits in 2 seconds and dies), YorSahj (some new spells (propably tank self heals?) go crazy during purple phase) and Warmaster (mostly heavy incoming tank dmg again, and some other funny new things). We didn't kill WBH today, so we go for the last 3 bosses on sunday. Madness will be interesting! And I will propably go holy for Spine.
I didn't play beta this much, so I hadn't much time to practise before DS. But I can say: I pretty much like the 5.0.4 changes.
Spirit Shell is cool. Before Morshok AE, Zonozz tentacle disco party, YorSahj Red/Green/Black AE, Hagara Frost/Lightning phase, Ultraxion anywhere, WBH before void -> use PI + SpS, then PoH spamming 4.3 style works good. I didn't had any Boss Timers due to Big Wigs Errors, but it still went pretty good.
I have ~3k spirit atm (+Spine HC Trinket), mana felt OK. As many already have pointed out in this thread, mana management is important again. Not as important as it was at cata release, but, as expected, I can't spam PoH 24/7 as I did a week before with 1,4k Spirit.
I tried a int/SP>spirit/mastery>crit>haste reforge and took PW: Solace. I believe that Zonozz/Ultraxion/WBH are bosses where Mindbender could perform better than PW:Solace.
Here are some Logs if you are interested (WoL still tags them as 10m NHC and kills are invalid, oh noes ._.):
worldoflogsdotcom/reports/rt-6u3ejoh94huph5ib/sum/healingDone/?s=1739&e=1949 is Morshok
Zonozz disconnect and not logged
worldoflogsdotcom/reports/rt-6u3ejoh94huph5ib/sum/healingDone/?s=3941&e=4332 is YorSahj
worldoflogsdotcom/reports/rt-6u3ejoh94huph5ib/sum/healingDone/?s=5050&e=5281 is Hagara
worldoflogsdotcom/reports/rt-6u3ejoh94huph5ib/sum/healingDone/?s=6496&e=6776 is Ultraxion (took red buff)
Imo, the most important thing about disc atm is: knowing WHEN to do different things. Use SpS, cast smite, PW:So (or mindbender, heh), use AA and PoH, shield, use single target heals. Practice makes perfect, and "new" Disc takes time to get used to it now (at least for me). Probably more than before, but it's fun!
Really looking forward to try holy, too. renew ALL the things.
excuse my english, as usual
