This must be one of the biggest changes to the EQ world yet other than the introduction of the various expansion continents. Even though they're evil I feel a bit sorry for the trolls - I played a troll shaman on EQLive for a while and was quite familiar with Grobb and its environs.
Still, for the time being Grobb will live on in EQEmu - at least until someone manages to capture the spawn data for Gukta
...
Maybe the trolls will get their own (new) city with the Ykesha add-on.
