Note we have no idea if its a DPS/Support like Bard is. Probably won't until June.

Most of the storyline after Prae can be done on your own, and currently most of the trials are very easy since you'll have people with you who are overgeared for them. I assume there will be "Normal" versions of atleast the Primal trials added alongside Heavensward (since currently only the first three have such, the rest are "Hard" and "Extreme" only). Chrysalis might be your first actual hurdle once you get to it.
