Only one of the same aura will have an effect on the team at one time! If one person uses Melee protection aura, and the team mates are in range to recieve the aura. No one can use Melee protection aura again untill the shaded stanza on the small "debuff window" has completely gone! Aprox. 15mintues!
Obviously the person with the highest lvl of a given aura should be the one to use it!
