Despite seeing it coming from literally the full length of the universe away, Ret Paladins are shocked and amazed that their ability to kill literally any class with any amount of HP, armor and resilience before any single Hammer of Justice goes down....
Was taken away.
Ret paladins weren't that good in PVP. There's a lot of exaggeration here, and a lot of people leaving out the fact that they're getting rolled by a dude with an S3 mace when they're wearing ALL BLOOS. Sorry, Doom, but pretty much anyone can roll you in pvp with that setup. Blame the game, not the class. Ret had one advantage over warriors in pvp - damage that wasn't affected by armor - and that advantage was taken away. Any nerfs now are, to be honest, appeasement to people whining because the class that used to be a free HK is now capable of competing in the top tier of arena.
Additionally, all the nerfs paladins just got weren't for PVP at all - they were for PVE - because blizzard said, and I quote; "
we want mana to remain a factor for this class in pve" - Nevermind that mana isn't a factor for any other DPS class or spec right now, and almost all the major class overhauls in 3.0/wrath towards mana using classes was to keep them from going OOM. Mana gains for retribution have been cut by 60%, and the end result is that ret paladins go from being capable of competing in the top tier of dps, and go back to hitting their heal button all fucking day because there's no rational reason to use them as a DPSer. Additionally, the prot paladin overhaul made them a strength focused tank, but someone at blizzard forgot to give consecrate some kind of attack power coefficient, so now prot struggles to output as much threat as a prot warrior or feral druid, while doing half the dps and having no utility advantage outside of (the now terrible) blessing of kings, which a holy paladin can easily pick up with five points in prot. What about AOE tanking you say? Well, unlimited target swipe and shockwave and huge threat thunderclap have something to say about that, and they actually scale, unlike Consecrate, now that blizzard has decided that paladins shouldn't be spelldamage based anymore.
tl;dr - fuck paladins, I'm rolling a fucking death knight.
