Almost all of WoW's troll types are gone. One tribe of jungle trolls and one tribe of forest trolls along with the Zandalari. Am I the only one disappointed to know soon we will only have two troll tribes left?
Status of the tribes:
Amani - Wiped out, again
Vilebranch - Mass ritual suicide at the end of Hinterlands
Shadowpine - Wiped out by blood elves
Mossflayer - Zombified and the living are too few in number to make a comeback
Smolderthorn - Wiped out in the Spire
Witherbark - Wiped out by Horde
Gurubashi - Wiped out, again
Bloodscalp - Wiped out with Gurubashi
Skullsplitter - Wiped out with Gurubashi
Shatterspear - Wiped out by night elves
Hakkari - Wiped out with Gurubashi
Atal'ai - Wiped out by green dragonflight and mercenaries
Drakkari - Wiped out by Scourge and mercenaries
Frostmane - Wiped out by dwarves and troggs
Winterax - Either wiped out by Horde/Alliance or joined Drakkari to be wiped out
Sandfury - Wiped out by goblins and mercenaries
Dark trolls tribes - Wiped out by Twilight's Hammer
Darkspear - Strongest tribe, continue on
Revantusk - Small, but still going
Zandalari - Most likely wiped out soon
