The Random Secondary Target System (RSTS) is a system deployed by Blizzard to make certain encounters harder and more challenging. The system will target someone in a party or raid but the target is never the player who is highest on the aggro list.

The system is probably designed to make the encounters more dynamic, otherwise most of the encounters would be "normal" Tank and Spank.
