Hexes combine three things that people tend to dislike: attacks, overt chance, and unnecessary complexity. I think DXV has said he wouldn't include them at all if he did Nocturne today. But I don't mind any of those things. I like hexes.
-Would a straight +2$, each other player recieves the next hex be better or worse than militia? Assuming tormentor doesnt exist of course.
Militia is generically stronger IMO. But hexes stack better, and attack from multiple directions. Some decks are hardly hurt by militia at all, but chances are there's a hex that will really hurt.
- Is the self- hex of leprechaun or cursed village more unpleasent?
Leprechaun, easily. The strongest use case for Leprechaun is to gain wishes, and that can lead to cases where you drew it too late in the turn, or had a partial dud. You can still play Leprechaun to gain a gold, but people tend not to do that, because they want to play around the possibility of getting Poverty midturn.
- If you could remove or modify one single hex, what would it be?
I don't think Delusion is necessarily the strongest hex, but it's rarely fun when you get it. If we wanted to preserve the flavor, we could replace it with a contraband effect, or force people to spend additional money to buy actions. I'm sure there are a lot of other unrelated possibilities too.
- Are they too complicated because of the states?
I don't like the states much, because they oblige me to get more cards out of the box. We just don't use the Envy and Delusion state cards, as they're mostly reminders. I wish Misery just exiled two curses instead.
