Dungeon Content: mostly easy, a good or bad df group can adjust this accordingly.
PVP: don't care
Crafting: fine
Gathering: fine
Leveling: its pretty easy with a nice variety of options, imo.
Buying a house: difficult.
Raids: fine, again a good or bad group impacts this.
Socializing (making friends): depends on the individual I think. but 14 gives you plenty of tools to help make buddies.
Special Events: depends on the event i guess. make it rain isn't exactly taxing. XD
