When I use the first skill I almost never get any debuffs and just get free gold. But when I use the second skill which is used to get rid of Bankster debuffs, I often get Bankster Debuffs. Is that supposed to happen, and if it is I ask that you please change it. Also, you can use your second skill which gets rid of your Bankster debuffs on your summoned units (I used the mustache guy from Golemancy).
All banksterism is meant to be risky, including the shenanigans to clean up the mess created by banksterism... I don't see them changing that -- except perhaps to make the debuffs steeper and/or more frequent.
High Interest Loan only has a 1 in 3 chance of giving you a debuff if you don't already have any. The real problem is the additional 50% chance of Payback per debuff you've already got. The 2nd skill is only suposed to give you a debuff 10% of the time. And I think you can use any skill on your summoned units, though why you'd want to is beyond me. It's a damaging skill, why not use it to damage someone?
