Heavensward turned what I believed to be a mediocre game into one I have sunk countless hours into, and it continues to be my favorite expansion, even above Shadowbringers, in the pre-Endwalker block. Nuanced and interesting character writing, superb voice acting and impeccable atmosphere make up an expansion that sent the standard for those going forward, culminating into my personal favorite final patch of any expansion (3.3) to this day. It's actual dungeon content is weaker than I remembered on replay ("Oh boy! Spooky rock cave #2!") but that doesn't intensely impact my opinion on one of my favorite video game stories of all time. And hey, it's free too. That's pretty cool.
