1) Only attack what the Tank is attacking. It is their job to keep the monsters hitting them while the DPS kills the monsters. It is hard enough keeping the aggro of the mobs they are attacking let alone trying to take the aggro off of some n00b DPS that attacks random mobs. :)
2) Rule 1 is in effect so the healer can focus 90% of his attention on the tank, rather than 5 different party members. If the healer can't focus, it means that if you have a less experienced healer you will probably TPK, and if you have a more experienced healer s/he will get a little ticked off and eventually the DPS that is pulling aggro will simply be allowed to die in every battle with little to no healing for the sake of the saving the rest of the party.
3) If you notice healers pulling aggro, try and pull the mob off them and if need be, die trying.
4) If you notice that you are pulling mobs, try and get as close to the tank as you can so it will make their job easier to take the mob off you.
