So on a fight like Ultraxion where I get the blue crystal, should I still stack haste there? What would be the point, the buff already gives you haste, and if I DA spam that fight.. crit is a bit RNGish for that situation, which leaves us with mastery.. I know you've said in an earlier post that this isn't the case, but I have been doing very well on Ultraxion this way. I will re-forge for next week and see where I'm at.
The OP suggests that we should balance the stats, yet some people have posted that HASTE IS KING. What is the real answer? If you can show me math that actually makes sense (i.e. x amount of haste = x cast time on GH/PoH) and how that haste rating relates to the balancing of other stats then I would have more direction. I don't really care about how haste affects Renew as disc, I don't even use Renew as disc regularly and I don't know any Disc priests who do. I'll re-iterate that I'm not a main raider (casual ftw) so I am not in heroics atm, not pushing them.. I'm just a lonely priest looking for the answers to life.
I'm really interested to see your logs for comparison. After looking at your armory, you and I are at very similar gear levels, but it sounds like we are having very different experiences as far as the stat weightings healing ultraxion in 10 man. I follow a haste > crit > mastery stat weighting personally, and keep mastery just about as low as possible. Here are my most recent ultraxion logs:
Two healing it along with a holy priest, and taking the green buff and then later the blue buff:World of Logs - Real Time Raid Analysis
Three heal wipe with the green buff:World of Logs - Real Time Raid Analysis
Three heal with the red buff:World of Logs - Real Time Raid AnalysisWorld of Logs - Real Time Raid Analysis
For me, this fight is as close to what the spreadsheet models as pure PoH spam as it gets. I cast PW: S on this fight only for the rapture procs, cast penance occasionally to get grace stacks on the tank, and cast prayer of mending on cooldown. At all other times I am purely spamming PoH.
As you can see, even with very little mastery my divine aegis is my second largest source of healing, behind PoH itself.
Please do post some logs of your ultraxion attempts with your current gear setup if you get a chance, as I'd really like to compare them to see what effect it has.
