Is quiver haste in now?

How do we know when things like this will go live? There's such a mishmash of rules and things on these servers. Some people say yes, some say no. Which is it?

Is probably the best consolidated list of when things go live on TLPs, that being said... quiver haste is a thing day 1, just not really relevant til like luclin when rangers are actually ranged dps

Quiver haste is not something that needs to be unlocked in progression, per se. Only a quiver with a WR % will grant haste, and then only if it is in a bag slot. (Quivers should have been allowed to go into the ammo slot, but that's another thread.) I have never seen an authoritative dev post for what the haste formula is; player guesses are just that, and all over the place. My own experience from parses has led me to believe that haste = quiver WR/4, others claim it is WR/3. The bow's delay is also a parameter in the formula.
