I'm also starting (until the patch comes out that is, when i'll be restarting again lmao) a completely legit character going from normal to nightmare, and possibly hell (although that will be exceedingly hard without uber gearz from farming and rushing).
My Account is TheImperials and i'm currently making a frenzy barb, my next character will most likely be an elemental druid. Feel free to hit me up on USEast so we can get a small squad going, better to do this type of legit thing in hell mode with friends eh?
LT Venom, that build u mentioned will never last in nightmare / hell.. I suggest you think a few steps ahead and think not how to finish normal, but how to last hell.. if your intentions are to play upper levels
