Crafting is pretty good to catch up on though its kinda hard near the 30s / 40s of it if you go pure crafting with no leves done... so I'd suggest doing it with leves if you choose to. I don't think theres a level for which... one can or can't craft though it can break a pocket but it also makes money if you know how to use the marketplace well, It can also make your relic weapon (The awesome bard harp/bow wep bard has in the artwork) if you level the right craft high enough though you can only get those after getting the mats and beating each primal in hard mode.
basically what you listed, dungeons (Some can be pretty fun when you're just learning with a patient or new party.) mmm... Boss / Primal fights in normal and hard mode theres coil...... which is apparently a hardcore end-game dungeon with a bunch of floors (I've never been myself personally) Gathering, Crafting, Fishing... and apparently more is to come but thats all I know of for now... ^-^;;
