1) #9: You linked your Armory. We can see it from your user pane on the left.
2) #6: Something new. "My damage went down" is so general as to be useless. If you noticed that your <insert ability here> was hitting for less, that's one thing, and specific notes (i.e. there was an Arms warrior both times, same group comp, same buffs, etc.) will lead people to help you figure out the problem. "I noticed my dps went down" is basically meaningless. Quantify things!
Read the rules, please.
Hi, I'm new here, but I've been reading the conversations the whole way through.
I just picked up the betrayer to replace my death's bite, and I noticed that in the next naxx 25, my damage dealt on several bosses actually went down. I'm not sure whether I was RNG screwed or to attribute this to other problems, but our hunters and rogues actually did significantly more damage than usual. Has anybody else been doing less damage since this patch?
