Yoshi-P stated before that progression in FFXIV will be more quest-oriented (or at least he implied it).
I've been giving some a go since 1.18 went live, and I can safely say that sidequests are now an enjoyable way to progress (because they give good sp and decent rewards), not to mention that they give interesting lore, with progressing stories from one sidequest to another, and some are REALLY good! some other hilarious lol.
At the very least, sidequests can hold it for us til 1.19 comes and more content are added ^^.
Do sidequests!
