World Of Warcraft: Dragonflight Review In Progress - Who Says You Can't Go Home?

Game Spot Reviews - Wed, 12/07/2022 - 19:30

World of Warcraft: Dragonflight is about coming home, in more ways than one. It's a homecoming for the titular Dragonflights of Blizzard's long-running MMORPG, who return to their ancient ancestral home to pick up the pieces and rebuild after thousands of years away. It's also a homecoming for players, who after years of languishing in WoW's unpopular Shadowlands expansion, get to return to Azeroth and all the familiar sights and sounds it holds.

Dragonflight, in that regard, is incredibly nostalgic, but not in the way you might expect. Though it without a doubt features the return of fan-favorite characters, monsters, and even gameplay systems, it never feels beholden or shackled by them. Instead, it takes those familiar elements and breathes new life into them. Whether it's the return of talent trees reminiscent of those from the game's earliest expansions, the game's updated user interface, its lack of mandatory activities, or the feeling of adventure the new dragonriding system invokes, Dragonflight miraculously feels both fresh and familiar at the same time. Even if there are some aspects of Dragonflight that could be improved, I can't help but be impressed at how a handful of new ideas, along with major facelifts to some old ones, breathe new life into Blizzard's flagship title.

Dragons, as you might expect, are the star of this new expansion. Players ride new, highly customizable Dragon Isles Drakes. The majority of the main campaign's primary characters are dragons. There's even a new dragon race, the Dracthyr, that is only playable as the new dragon-themed spellcasting class, the Evoker. The Dragon Aspects Alexstrasza, Nozdormu, Wrathion, and Kalecgos all play key roles in the game's initial story campaign. To see them all front and center for the first real time since 2010's Cataclysm expansion is part of what makes Dragonflight feel so nostalgic, signaling a return to the high fantasy of Azeroth after nearly two years of the dark, dour, and death-themed settings and characters of Shadowlands.
