So here I am, consulting Icy Veins forums. I am a Frost Death Knight, with an iLevel of 885 that is REALLY struggling with my dps. I'm running a BoS build because it was recommended to my by other Frost Dks. I have done a ton of research about this issue to no avail and I really need some professional help. 
Here's my armory and my charts for my last Heroic Nighthold with my guild
Armory: http://us.battle.net/wow/en/character/dalaran/Kumunyo/simple
Dps Charts: https://www.warcraftlogs.com/rankings/character/21405978/latest#
Note: I do see that my Haste is incredibly high, I'm currently working to get the 4-piece tier gear.

I'm currently getting somewhere between 250k and sometimes 270k during boss encounters (according to Skada) in the Nighthold. Everyone keeps telling me that its my iLvl/gear, but I'm not sure. I have everything enchanted and gem'd.  I have been trying to acquire gear with more haste, because I feel that  it is my biggest issue. I'm only at 20%. Any thoughts or opinions would be greatly appreciated. I am also currently going by the Icy Veins recommended rotation. Maybe not to the exact letter, but I feel like I have a lot of downtime. Which is why I am suspecting its all due to low haste.  I have linked my profile and logs below. Thank you!
