You'll also eventually want to get Lancer(LNC) to 34 for Invigorate and Blood for Blood, as well as Internal Release from Pugilist(PUG). Second Wind/Mantra from PUG are nice as well but aren't absolutely essential, but you'll definitely want to obtain the others I mentioned to perform much better damage.
Archer is okay for soloing but in group content you'll definitely want to have Bard unlocked and play as that since you get DEX/VIT boosts as well as access to abilities and songs that you can only obtain/use as Bard. Also as ARC/BRD you'll want to put all of your points into DEX for the dmg boost.
