Just finished normal mode, bought the game yesterday but didn't get to play too much then. Most challenging so far was actually the diablo fight. Not diablo himself (party of four witch doctors, just stay at max range) but when he summons the shadow clones. they insta-killed us all twice, third time one guy manages to break away with a sliver of health, and somehow survived and revived us. Upon the second summoning of the shadow clones, the other 3 die instantly, and now it is me on basically no health to run around and revive them. But I managed and we beat him.

I am not sure if I should be starting HC already tomorrow (all I really ever did in D2 was hc) or play on in normal to see the other difficulty levels, as I hear it becomes really tricky to not get one-shot to death.
