What's the current price? 25bil seems a bit too much, especially for the players in C rank who can barely afford it.
I get ~12bil per sell at Z which is about every 10 seconds. 50mil is way too small, what I'm suggesting would have a high risk but a good reward for the lower players, as well as higher players.
I think the plugin should just be removed. High-end players can easily purchase it and likely dominate it. They're likely to win 99% of the time and the winnings are just a fraction of what they usually get in one inventory sell. Not very beneficial to anybody except the rare low-rank winners.
I agree that the tickets should cost more. I think 25 bil is too much. Since the max lot buy is 10, if each ticket costed 2-6 billion that would make the pot have a decent amount, and lower ranks will still want to buy tickets.
The problem is, there's such a big difference between the amount of money between lower and higher ranks. So no matter what we change... either the higher ranks won't get anything from the pot, or lower ranks can't even participate.
25bil is a little much, considering there are a LOT of people that are in the lower mines who probably need the money more.
