OK I have 0 experience with Diablo so prepare yourselves to read really silly questions!
a) When I finish i.e. normal mode, do I start again from lvl 1 on nightmare?
b) Is there anything different when I play online with my friends, like dungeons etc or it's just the same campaign with more difficult monsters scaling to the number of party members?
c) Is there anything different on the campaigns between different classes? I would like to level most classes but if it is the same game over and over, especially if it is the same difficulty, I highly doubt i could even level a 2nd class (currently levelling a witch doctor but barbarian looks badass, i partied with a friend of mine on normal, he cleared whole groups before i cast a single spell)
d) Do we know anything about PvP yet?
and any quick tips about professions would be appreciated. Can I be blacksmith and Jewelcrafter (or w/e that gem thing is) at the same time? SHould I be saving my gold to train these professions or there are other useful things to spend my gold on?
I tried googling these questions but apparently I am the only dumb one not knowing these!
TY for your answers
