Wow is completely different game, skipping content there does not hurt as much as it does here.

Without going through story, you are missing a ton of content that is available to you and still relevant due to the cosmetics. It wont work in ffxiv as max lvl content is not large enough to sustain your interest for so long.

I still feel guilty skipping ARR and wish i never did, as its story after praetorium is really interesting.
