So while we pray or buffs in 8.0 PvP, Blizzard seems to have new pain in store for us ...
Decomposing Aura gone for Frost DK (the only thing close to a mortal strike effekt, and allowing us to kill somebody despite our non-existing burst. BoS is too easy to counter, Lichborn will most likely not fix that)
Tundra Stalker gone (to get the damage plus you had to sacrifice damage before, but I was looking forward to the new Deathchill)
Overpowered Rune Weapon gone

Chill Streak buffed, but with the low bounce radius and the mobility existing this ability will never deliver.
Lichborn. Completely useless at the end of the day, besides against melee pure cleaves. Maybe.
Wake up guys and cry out. We need a competent person that plays the class to make changes, not a numbers crunching data scientist.
