Officially the Drakkari Tribe is no more. The bulk of their tribe were wiped out during the Northrend Campaign, either by the Scourge or by Alliance/Horde adventurers. What few Drakkari remained allied themselves with the Zandalari during the events of Mists of Pandaria and they, along with their Chieftain were killed by Alliance/Horde adventurers.
The last known Drakkari that still lives is Speaker Malaka’raz in Zuldazar, who confirms the fate of the tribe as of the events of Battle for Azeroth.
