Ive been wondering about this for some time, hope someone will be able to answer. Why had Azmodan been waiting 20 years before he finally decided to invade Sanctuary? My only possible explanation is that he still had to deal with Belial, but that wouldnt explain why Ghom would want to kill you for killing lord Belial. That being said, I take it those 20 years are not about them fighting each other and then becoming allies.. Also, how did Baal summon his army? At some point he is all alone, trying to get his soulstone from Marius. The next cinematic shows his big *** army. Can someone elaborate? I dont want to answer myself by saying the soulstone gave him the power to summon the army from hells. That would have made the whole Worldstone useless..
