Ret paladins weren't singled out or anything. A lot of damage classes feel like they have very slow throughput in pvp right now, and most healers feel weak relative to the stronger damage classes. Once people are wearing the new gear, damage relative to healthpools (i.e. burst) should be quite a bit higher. I also expect healing will scale up more than damage will, since resilience is so much stronger than battle fatigue.
In the meantime, although it might not make a huge difference, your character can definitely be better optimized. Let me preface this by saying I don't mean to be condescending or anything; I'm just assuming you don't know this based on the state of your character. I've given you links to the item names so they're easier to find ingame. Your cloak has a stamina enchant instead of
crit, and your
shoulders,
bracers,
belt,
legs, and
boots are all missing their enchants. In addition, most of your gems are also non-optimal or missing. For your meta, you should probably be using a
reverberating primal diamond. Spell reflect is nice when it happens, but it's so rare that you can't rely on it. Throughput is better. You're using a few full resil gems in yellow sockets, which I believe you should change to
str/haste. Also put one of these in your empty boots socket. Change your gloves' full pvp power gem to
str/power, as well as the empty socket in your belt. Lastly, you'd want to put full strength gems into your legs' red socket and belt's enchant socket.
