Vindication and Hammer of Justice nerfs

More incoming PvP nerfs for paladins in today's hotfix:

• When immune to the stun of following abilities, Maim, Bash, and Hammer of Justice will no longer cause player spells to be interrupted but they will still interrupt NPCs.
• The Retribution Paladin talent Vindication no longer reduces the targets stamina or intellect but does correctly lower agility, spirit, and strength.

The first one means that sooner or later, the diminishing returns from the stun effect of Hammer of Justice will make the opponent immune to the silence effect as well as the stun effect.

The second one turns Vindication into a completely useless talent. Reducing the opponent's agility, spirit, and strength is not exactly useful.

So within a couple of weeks, several paladin PvP talents have been nerfed: Hand of Freedom, Eye for an Eye, Hammer of Justice, and Vindication. And of course the nerf to Exorcism so that it no longer could not be used on players and their pets. Even our retribution aura got nerfed!

If retribution paladins are so overpowered in PvP that they need these nerfs, why are we not seeing more of them in the higher brackets in Arena?

Patch 3.1.3

I took a week off from raiding and spent only little time online, mostly doing dailies with my alts. I have four level 80s and they all need that darn Sons of Hodir reputation.... (two exalted so far)

This week it seems like we are getting a new minor patch. For paladins, it's all about PvP nerfs (again...)

• Eye For An Eye: This talent now deals 5/10% of the critical strike damage taken by the paladin back at the attacker.
  
• Hand of Freedom: The base duration of this buff has been reduced from 10 seconds to 6 seconds.

And then we have yet another Ulduar nerf:

Mimiron

• The flight time of Rocket Strikes has been increased, and Rocket Strikes will try to prefer players at range.
  
• The Leviathan Mk II component of the V-07-TR-0N will become stunned during Phase 4 when the VX-001 component begins to cast the P3Wx2 Laser Barrage ability.
  
• Proximity mines now deal less damage and have a lower duration. A small arming time has also been added so proximity mines will not immediately detonate on creation.

Now, I must admit I don't mind the rocket nerf (I've got killed more times by rockets than I want to admit), and phase 4 could be a bit messy if the Laser Barrage occured just after a Shock Blast and the tank is repositioning the boss. But, seriously, why the nerf to mines? Did people actually die from these?
