Troll names are sharp and short, with surnames full of voodoo, bone and jungle. Warlocks wear names with a bit of menace. Troll Warlock is one of the new combinations in WoW Forever, so expect a lot of players to try it at launch.
Every character in WoW Forever has a first and a last name, and only the full combination has to be unique in your region. So a popular first name is still usable with a less common surname.
Example names: Gazkai Darkmaw, Okkaja Wildshaker, Hexaji Frosthunter, Gloomwa Tidescar, Han Blood, Vulzi Tuskhunter, Xalmon Shadowtusk, Baijatha Smoldertalon.
