As we stated on our Home page there are 3 primary roles that MMORPG players have become accustom to and they are:
Tank
Healer
DPS
by the way the model used here is one of our MIST ELVES.
Yes, she is sexy and she knows it 
Tank as primary role will grant the following:
+100 health
+50 Armor
+10% dodge/parry
+2% health and aggro gain per player while in a group.
Healer as primary role will grant the following:
+5% to healing spells
+5% to healing spell range
+2% intelligence boost
-2% threat per player while in a group.
DPS as primary role will grant the following:
+5% damage
+2% power(mana) regen
+2% speed(haste)
+2% damage per player while in a group (this does stack with the +5%)
By design and definition Tanks take damage, DPS cause Damage and Healers restore damage.
