All in all, Battle For Azeroth is in all things a true expansion to Warcraft; it is a continuation, a plateau for the game to simply continue existing.
Destiny 2: Curse of Osiris feels like rushed DLC that was never expected to fix what the glaring problems with the base game. Rather than attempt anything, the lazy additions come off as what would in any other game be added in a free content patch, a skeletal selection of missions and events that are both minuscule in scope and forgettable at the same time.
Legion is everything it was promised to be and more; a part apology letter, part defiant challenge to any other games in the market thinking the old wolf was weakening. It is a love letter to its playerbase, to its most committed players, as well as the most approachable welcome to anybody coming back or starting fresh. It is the anti-Warlords of Draenor and, with the exception of FFXIV, the greatest comeback possibly in gaming history.
