I'm kind of curious as to how someone hacked your account.
So I lost my old account, created a new one, and I have a single level 32 Paladin right now. Honestly, for myself, I really like the Gem Skill system. My main Attack right now, I think of as "Wrath of God." It's Firestorm junctioned with Added Lightning. I am going to add an Increased Fire Damage to it, as well. I tried getting it to Leech health for me, but that didn't function, so I have my Health Leeching gem Junctioned with a flaming hammer attack, currently.
I just finished Act 2 on Normal difficulty, which is further than I got before. I don't recall ever beating Act I, honestly. I think the Ship Graveyard was where I stopped.
