In Zulaman and Zulgurub as well as Zuldrak, we have seen Trolls channel animal Loa to gain power. It is certain possible that certain Troll Priests could call on their Loa for similar empowerment, and thereby gain Druid-like powers. They have the pick of the pack in terms of animals to worship. What is really intriguing to me is which set of Loa player-character Troll Druids might call upon. As Darkspears originally hail from Stranglethorn, they might call upon the jungle Loa of Zulgrub about Grand Fantasia Online Gold, assuming they are now freed from the influence of Hakkar. On the other hand, Zulaman offers more immediate analogues to current Druid forms, including Bear, Cat, and Bird Loas to get Grand Fantasia Gold
For me, the Stranglethorn bunch seems much more likely, actually. If you have ever quested in Zabrajin, you do some scouting on Lost One Druids in Feralfen Village for the Troll Shaman Seer Janidi, and she says, No self-respecting Darkspear troll engages in bird worship. Their spirits are weak, capricious, and best left to the Amani. On my Warlock, I keep forgetting that I could avoid a lot more corpse runs while soloing if I used my Soul Stone on myself and kept a Health Stone summoned. Sure, In theory I might get a group at any moment and then have to deal with my stone being on cool down, but honestly, I am a DPS Warlock to buy Grand Fantasia Gold, they are a dime a dozen, and the chance of me getting a group when I am not actively look for it are probably slim. So there is not really an excuse not to self-soulstone.
