Unless they do something to really mix up how BLU works next update (Which I severely doubt given the calibre of the skills we have now), it will be the same with level 60 BLU, except there will be some harder masked carnival or solo instance. To get the skills you'll still need to grind get carried through primal fights for max efficiency, (especially with the cap moving to 80 for other classes).

Also not to bear in mind is overworld leveling will be more tedious now, Heavensward overworld mobs are tankier, and you can't just thousand needle cheese like you did before.

Overall they've made a "Solo Oriented Job" that is anything but. Personally I would want it to be a full job, with the skill collecting staying as a mini-game they update every now and then that doesnt work in current content, but there are other threads talking about that.
