So I came into the rather embarrassing situation of having to have raid lead bench me last night after repeated pulls with very poor DPS. We're working on Garalon and the minimum acceptable DPS for our strat is 85k, I'm barely pushing 60k. Our raid lead wanted to transition to a new strat where range no longer use the circles, pushing my potential DPS even lower so I asked him to replace me. You can see in future logs the other ranged DPS had no issue keeping DPS up even after the change.
In the previous weeks I was willing to blame it on a lack of gear and optimization, but I spent the last week or so fixing that. I'm not sure where else I can make up such a huge difference. I have less obvious but similar issues on a large number of fights, significantly lower DPS than my gear alone can account for.
Stat weight simmed out to be fairly close to even between mastery and haste.
I really appreciate any insight anyone can provide. If this performance continues I will be forced to step down from raiding entirely.
