I decided to start tanking with my Level 15 Druid but when i went in and went into Bear Shape Shift and I go in with 2 Paladins healing my and I gather every mob up in that one area and as soon and someone shoots them, they run off, one guy suggested to attack them to keep my threat level up, so i turned on auto attack, and still they run.

So how do I keep them in a bunch with out them running off on me?
