I only use "DPS Rotation" macros in lowbie dungeons so I can do something else (watch TV) while running them. Cause there isn't much to do aside from spam Fire 1, Blizzard 1, with the occasional Transpose and Thunder 1 x_x

Aside from that, I have Skill Macros to inform other players that I've used them (Virus, E4E, Resurrection) or as a little reminder for refreshing skills such as Shadow Flare. Just remember that once you use another macro before one finishes, it cancels the first one queued.
