Jack of all trades master of none, Can't Tank, Can't Heal, Weakest DPS. Jack of what trade?, Master of necromancy
harsh DPS checks, RDM can't carry any new party through anything unless it's a geared RDM in a group where people have gear. good luck doing that week one, two, or 3 even. RDM shines when the RDM knows the content and some of the people have cleared or have brain cells in a group of players who can't actually do the content. it's a job that exist to carry bad players and probably get some milage in early blind progression.
