THIS COMMENT MAY CONTAIN SPOILER, SKIP IT IF YOU HAVEN'T PLAYED THE MAP:
This is really epic, almost all aspects are impressive.
However it got worse and worse after you meet Lilith.
Lilith is a very important character in Diablo I believe (without her, the world sanctuary wouldn't have existed). However the Boss fight with Lilith is ridiculous. An important character with only drain and finger of death?
You better remake the boss fight, and make it more epic :)
So does diablo, i mean well he is good but it is not epic. His abilities are not good enough.
Still this map deserves 5/5!
