I'm struggling as well. Tried a Storm Amazon untwinked and it was easy to get the first (easy) act 1 and 2 charms, but it seems the item requirements afterwards get steeper (compared to other chars). I think I will start with a trap rat (medium gear almost only easy runewords).
General question: Are most of you starting solo or will there be leveling games? - I'm a bit torn, on the one side it's fun to get there on your own, but leveled many chars in the last 2 weeks and somehow i just wanna get it done
