Last night, for the first time since patch 3.0.2 was released, I raided as shadow. While I thought I was at the hit cap, spells were still missing. I know that 17% hit is now required, and the hit from talents was reworked.
I have 3 points in Misery, 3 points in Shadow Focus, and 140 spell hit. I shouldn’t have any spells missing (139 is the new spell hit cap, with talents).
I figured Misery was bugging out. Apparently other players have been having trouble with Mind Flay (which happened to be the spell I was missing with). Eleven seconds of research brought me to shadowpriest.com’s list of currently known bugs, which had multiple listings for Mind Flay, including it “randomly” missing.
Current theory about why it is missing: Raids are reaching the 40 slot debuff limit and Misery getting “pushed off.” In the WotLK beta, the debuff limit is much higher, so this wasn’t happening there. Only on the live servers. Hopefully Blizzard will roll out higher debuff limits with WotLK.
Other reported problems with Mind Flay include:
- Ticks not being evenly spaced.
- Last tick being cut off.
- Not working with properly with [nochanneling] macros.
Ghostcrawler (Blizz game developer) addressed the issues with Mind Flay today on the forums, saying:”We’ll look into it.”
I wasn’t watching Mind Flay ticks as carefully as I probably should have been, but if we are frequently losing the last tick of it, and sometimes have a 3% miss chance on it even when capped, that could be a 10% or more reduction in our raid DPS just from bugs with that one spell. Mind Flay generally makes up about 1/4 to 1/3 of our raid DPS.
Hopefully Blizzard does look into fixing that soon.
Just as an update…
We rebuilt Mind Flay to make it work under the new system. It’s now much more like Arcane Missiles, so the possibility does exist you can clip some of the ticks. It’s possible for us to rebuild the spell again, but that will mean changing a lot of talents (which introduces the possibility of bugs) so we need to make sure this is absolutely necessary first.
I would think about a 10% loss in DPS due to these bugs would constitute an “absolutely necessary” fix. One would hope, at least.
