"Rumor of a beastmaster class"? Heh. People have been asking for EQ1 Beastlords to be added to EQ2 since beta, and SOE's always said it will never happen. In fact, they even made it so the forums automatically converted the world "Beastlord" to something else ("Rick Astley" was one for a while, if I remember correctly) because people brought it up so often and the mods were sick of it.

I loved my Beastlord in EQ1, it was my main and I've never played a class with the same interaction between master and pet in any MMO since, but I am pretty sure that this rumor for EQ2 is nothing more than 5 years worth of wishful thinking.
