God is sustainer of the universe , I ' m not sure he intervenes beyond that in a surgeon ' s surgery , nor do I think it much matters for theism if he does . There is certainly not enough there for a book . <| sep |> EDIT if you just take class x over class y , you still choose player alpha over player beta for that specific class . Because of different fightsphases . Every class has some talent making it worth to include , even if we just look at Bloodlust and so on . Shadow priests do a shit load of DPS but not over the whole fight . They are perfect for nuking , but other classes are better for bursting high priority adds . So , there will always be a mix of different classes . And when you choose one player of that class , you choose the one with the correct legendaries 50 k more DPS
