Since its already your 2nd play through, you should go play in high difficulty. It really makes the game more challenge and interesting. Mobs are hell lot harder to be defeated with higher hp. It takes me 5 casts of explosive arrow, each dealing around 330 damage, to complete wipe out a group of imp which is level 20, 21 where I am level 22. Ranger really going to use mp potions like nobody business.
