Nostalrius Begins - Quality wow vanilla realm (1.12)

Anyone else feel that the dire maul east herb farm has been stealth nerfed? Getting worse droprates than usual unsure if just rng or an actual nerf, would love a response from other farmers out there

RNG is RNG.

Took me almost 40 runs to get Whipvine Cord to drop. Seemed like it was bugged to not drop.
