Alright, after about a entire week of this happening, I figured it was time to post to see if anyone else is having this issue.
I am a DW DK using a 0/43/28 spec (http://talent.mmo-champion.com/?deat...h=131221040506).
So, after alot of testing in raids (both 25 and 10) I have come to the conclusion that there is something seriously bugged with frost skills connecting with targets. Here is more info.
Lets say we are fighting Sapphiron. Obviously a giant boss. About 10 seconds into the fight, I have both my diseases on the target, 2 death runes, 2 frost runes up. As this spec its best if I spam 4 Icy Touches. So I spam all 4. The animation goes off but no damage what-so-ever registers. It uses the runes and casts it as normal, but the skill just doesn't connect. Infact it does not even show damage on the boss, a miss, a resist, nothing...
So after 4 useless Icy Touches, I try a Howling blast. Nothing. Plague strike works, blood strike works, all melee abilities connect to the boss without any issue. Now, I figure something is bugged on my end, so I ask the tank to take 1 step back and reposition the boss slightly. Howling Blast connects for 9k. I think to myself, awesome i connected!
So I start prepping skills on boss again, Icy touch 4 more times. First connects, the next 3 don't register. At this point I am kinda upset, and try another HB. Nothing.
So Maybe it was how I was positioned to the boss, so I move to the other side. Nothing.
This is my experience on almost every boss in Naxx. I never have issues hitting my IT on trash, but for some reason my HB is having issues even on trash.
Now, YES I am at skill hit cap, infact I am about 5% above it. After about 4 bosses of this happening to me last night, I said screw it and respecced into Scourge Strike. No problem what so ever, all IT hit, everything was fine.
So here is the break down:
Something is causing 90% of my FROST skills to not register on bosses when I am specced 0/43/28.
Something is causing my Howling blast to occationally not register on trash.
When the target is moved, the bug goes away for 1 skill then is back.
Is this a known issue? Because basically with the HB cooldown being removed, I would want to use this spec more and more.
It might have to do with the fact that I am proccing Killing Machine a ton being that I am DW.
If videos are needed I can record this weekend. Frankly I find its odd that it is only Frost "Casting" skills, nothing else. Is anyone else having this issue?
