i think i finally hit level 60 at the start of the luclin era. personally i soloed seb, as it is fairly easy and decent cash, imo. i enjoy being able to tank the mobs too. some pop stuff may not be to difficult, PoD or PoN. at 57 is the hedge in PoN soloable?
as a side note, when i leveled my pally up i boxed through Ldons. it was really good xp for him. not sure if you could solo it though.
