Accuracy is a huge issue, especially for a tank character that in some sense relies on leeching life for survival, also you won't have the points to spare to up crit chance without a larger opportunity cost. It's very viable to skip doing damage nodes until endgame and just pick up tank passives along the way to ~60. That's more of a HC playstyle, but it should do you well. Dual Wield Swords is, ummm, suicide =/ As for your specific encounter, the cobras are what are killing you, kill them first and dodge their projectiles as much as you can.
