Gotta love image as text. I'm old school, and those rules just make guided arrow and telestaff king.
1. No one ever won a duel just by ATD at level 30, so limiting that doesn't even make sense. Sounds like the creator, who only knows how to use MS Paint, died once to thorns then banned it.
2. Increased speed having 2 skill points isn't going to make any difference unless you are running marathon across Act 1.
3. Everything else is quite arbitrary and clearly is a result of pigeon-holing gear choices. Like Sacrifice or Concentration charges, no one ever claimed those were OP. 8% life steal, so you can wear String of Ears, but 9% life steal would ruin the game, right?
