Realistically, WoW has done the most dirty work against trolls. The deaths of Zul'jin and Vol'jin (and Rastakhan too), turning the Amani trolls into Duran's experiments to be a mix of orcs, trolls and reptiles, the weak appearance of trolls, demoting them to some tribes, and they had the largest empire ever before the rise of elves, etc. Seriously, why does Blizzard hate trolls? You can say what you want about BfA, but even though they had enough focus on trolls, they barely show them today. Rohan, Talanjii and Zekhan are the only ones left of the main trolls, but they barely appear at all after BFA. JUSTICE FOR THE TROLLS! Enough of World of Elfcraft.
