Imagine you and your raid are facing Sargeras,the final boss of Warcraft. For ths particular encounter the raid can be bigger(up to you). Give him stats and abilities(actual numbers are not very relevant).
Hit points: 100 Billion
Abilities(passve and active):
Ability one -....
Ability 2 : -.....
And so on.I will not write my vision yet since i'm on a crappy laptop and the keyboardsucks until tommorrow. But i'm interested in seeing how people imagne the fight.
