Rukhmar tag

am standing there waiting for the spawn on my hunter and a druid is there with me. It manages to hit Rukhmar and kill it but I don’t get the tag because it doesn’t come within 40 yards of me!! I hit one of the phoenix it spawns but that doesn’t count apparently.

I want to know how a druid, who has the same range as a hunter, can hit the bloody thing and I couldn’t. and yes, I had it targeted obviously

Moonkins do not have the same range as Hunters - they actually have a +5 yard advantage due to the passive Astral Influence.
This also includes talenting Balance Affinity, as it also grants other specs Astral Influence.
