RDM discussion threads always just turn into SMN discussion threads.

Mobility and Raise and all that is nice, but the real issue is the damage. It's what is selected for over any other attribute when picking group members.

Go play RDM for a few runs and tell me you aren't working your butt off with juggling procs/swiftcast/accel/etc only to get out-done by a SMN with a rotation so braindead you could teach it to a goldfish.
