Group synergy question
So, I haven't been around since the very end of 1.08 so I doubt very highly if anybody remembers me. However, a few friends and I have come back to play around a bit. We will be playing from scratch, untwinked. There will be four of us as follows:
Barbarian
Wolf Druid
Trap Assassin
Sorceress
I will be playing the Sorceress. We will, of course, be playing in Hardcore. My question is this: seeing as how the assassin will more than likely end up going fire traps, it seemed to me that I should go for a cold build. Was considering either blizzard or orb/ES. My other thought was to have the assassin go lightning traps, and have me go fire. Between heart and BO, though, will I even need ES? Anyway, if anybody has any thoughts, please respond =]
