I think Frost DKs got the first treatment with the implementation of Outbreak and then having their blood runes permanently converted into death runes. Afterall, who wants to waste precious uptime on a piddly Blood Strike before you can get a death rune? Just get straight to the point and bring on more Obliterates and Howling Blasts.
Somewhere around this time we also started to see more and more snares become auto-applied instead of requiring an additional GCD.
We have since seen Ferals recieve a Glyph to cast Savage Roar with no combo points, Rogues being able to add combo points to a target prior to combat with Premeditation, Rend removed from the game so Warriors don't have to waste the GCD to inflict their bleed, and now Unholy DKs are having Plague Strike inflict Frost Fever in addition to Blood Plague as well as having the runic cost of Gargoyle removed altogether.
Starting a battle short of 30% Holy damage and 10% crit seems a little more detrimental than what preceeded any of the above quality-of-life changes. It seems Retribution is being left behind as the expected efficiency of a melee class is being raised.
The worst part is that Ret has actually been in this position before when there were multiple Judgements on a shared 8 second cooldown. The first 8 seconds of any battle were lost because that first Judgement did not deal any damage, but instead applied a debuff to increase Holy damage to the target.
We found out in BC that starting a battle 8 seconds behind the curve is not effective. I'm not sure why they decided to put us right back into the same spot by having to build up for Inquisition.
I would like to see Rets given some form of assistance with getting Inquisiton up at the start of a fight and when it falls off during CC.
