Yeah, you can play "pvp" with starter edition accounts, that have this limitations:
- Max level: 13
- Max difficulty: Hard (enter in the game and up the difficulty)
- Blacksmith (blue gear) and Mystic access.
- Rare items can be obtained in npc's or killing enemies.
- Legendary items can be obtained killing enemies (Leoric in first time drops Leoric's Crown).
- 5 characters per account.
- Few skills available, but duels don't are oneshot.
- No gems, no paragon, no items level 70 converted to level 1.
- It's free create a starter account!.

Old video (when ancient spear was cool xD)
Would be cool make events with this accounts, are free and maybe to the people like it and try to find a balanced duels (like LLDs in D2)
