I thought I would farm some Pirate Warriors today!
Made a counter deck for it and only faced every bad matchup I could find with Dragon Priest, 
I'd run Ooze and Chillmaw, but that does nothing against reno decks except for when they play Medive and Jaraxxus. 
Lucky me :p 

PS: I've picked Dragon Priest for a 60 gold daily quest. But It didnt worked out for me.
Do you guys also have those moments when you switch deck and the meta looks like its all shifted?  

so ive been wanting to play arms more than fury in mythic plus  but when i simed my self it said i should be doing 400k while i only do around 300k average ( dungeon) ik this might be for a raid but either way its no where close to 400k .

i find myself at a lack of procs for CS and stuck with no rage while everyone  else in the group is doing damage while im just sitting there waiting on a meele swing

My raid member is having issues doing reasonable DPS as a Fire Mage and I lack the knowledge to help him.

I can get more details from him if required. He is getting mad at himself for not understanding what he is doing wrong. And my knowledge of classes stop outside of melee.

recently back to WOW, used my lvl 100 boost on my Combat rogue and my DPS is half of what it should be. My Item lvl is about 670. My single target is about 16K and my multi is around 21K. the DMG calculators say it should be between 29K-36K single and 34K-50K multi. I have no idea what I'm doing wrong. i use instant poison and Toggle Blade Flurry when its a multi target event and of when single. I Use Anticipation over mark of death as i find it easier.
 
My rotation is start Ambush>Revealing strike>SnD
then i pop my cool downs normally in this order. Killing Spree, Shiv, vanish>ambush>Preparation>Vanish>Ambush>AR
Then SS>5X CP>Eviscerate till any cool down resets while keeping SnD, Revealing strike and Internal Bleeding from Kidney shot up as much as possible. 
 
I don't know what i am doing wrong, is it just being accustomed to the game? I've seen many videos on Rogue rotations and they don't do much more than me. 
 
I need help and have no idea whats wrong Please Help me.
