I enjoyed Heavensward.

Everything from the zones to the music to the story were all very well done in my opinion. The new jobs had balancing issues, won't deny that, but you can't deny they became fairly popular. People had wanted a gun-wielding job for ages, Dark Knight was hyped up well, and Astrologian brings together the best of WHM/SCH gameplay with Yu-Gi-Oh thrown in.

I'm not worried too much about Stormblood. They're dropping PS3 support, so we may see about as much content as Heavensward gave us, but also an influx of new Quality of Life changes, such as the expanded inventory space. It's those (and Red Mage) that I'll be looking forward to in Stormblood. If they don't arrive immediately, I'll wait for the patches. If Red Mage is broken and virtually unplayable at first, I'll wait for them to fix it, and work on it in small, non-infuriating increments. Farm gear for it on Black Mage.
