If the datamined Ret Paladin changes go through, hunters may as well just stay out of PVP altogether.
Slow on judgment, slow on blade of justice, templar's verdict from 25 yards, self heals out the ass, auto-WoG at 40% HP.
There is just no way a hunter will beat a ret...EVER. And ret is an extremely popular spec in PVP, so there will be lots of them around.
Personally, I'm thinking of quitting the game for now and then roll a ret next patch. It's just pointless to keep playing hunter at this moment that we know what's coming.
Unless a MM revamp also comes soon, hunter will be garbage tier for pvp simply because rets will be so anti-hunter, and there are tons of rets, but Blizzard has no idea what to do with hunters so I won't hold my breath for a revamp.
