Incorrect, in a raid environment (so with totem of wrath), a Ret paladin needs exactly 1019 haste rating to bring CS to 3sec CD (counting Judgement of the pure and Totem of wrath).
In fact, i just had to reforge half of gear from hit/crit to expert/haste, i'm actually at haste cap with 27% crit and 5700 AP unbuffed.
