I'd like a skilled frostie to take a look at a couple logs and see if you can see something I'm maybe missing.
Last week on Saurfang25hc http://www.worldoflogs.com/reports/1...?s=1434&e=1625
This week on Saurfant25hc http://www.worldoflogs.com/reports/d...?s=3762&e=4005
my armory: http://eu.wowarmory.com/character-sh...cn=F%C3%A1mine
The only difference, gearwise, from last week and this week is that I picked up HC Bloodvenom and normal Havoc's Call. Last week I was using heroic Frost Giant's Cleaver x2 (RoFC on MH and RI on OH). Last week I was Arp capped at 100%, this week it's 98.7%. Last week, my hit was 253 and this week it was 285. The other differences are negligible.
My concern is that, across the board, my average damage was low this week. Oblit's were only slightly higher on average "hit" last week, but 1.5k/1.2k higher on average crit last week. My white hits and crits also show roughly the same decrease this week over last week. My frost strikes are roughly the same. Basically all of my physical damage this week was lower than last week, with 2 weapon upgrades. Is the loss of 18 armor pen really that significant a change? or is there a missing buff that I just didn't see?
