Befallen  

Yeah! Why doesn't Verant give me experience and loot on a silver platter? And why wasn't my character born with a silver spoon in its mouth?

Seriously, dungeons are designed for GROUPS, not soloing, at the levels that you will get good experience from the mobs. Befallen is SO easy to get to that there's no excuse not to grab 1 or 3 of your friends to go with you rather than trying to solo. Even better is the fact that since it's such a low level dungeon (unless you have the sick and twisted uber-Befallen on your server), that it's pretty easy to hire upper-level "help" for a nasty CR (e.g. a pair of 30 players or a single level 40+ player).

Learn those dungeon fighting/grouping skills now while the learning cost (e.g. death and CR) is low, otherwise you will eventually lose a fully geared corpse in some Tunare forsaken level 60 dungeon someday.
