Hey, I'm just feeling my way in the dark here, I'm not sure I want the responsibility of anyone following my lead!
When you say the three positions, do you mean 1500 in total per orbit, or 1500 in addition to what they would have paid in SB+BB? I think even 1500 in total might be a bit much if someone becomes a zombie early on (and would be crippling if it was in addition to the regular blinds). In L1 that's the equivalent of posting 30BB per orbit as opposed to 1.5BB for a human, though it does depend on the zombie stack size.
I could be totally wrong though, the point of this thread was to get my ideas out there and have those with more expertise than me (basically anyone on PCF) point out the flaws and issues so I could maybe implement this with some success.
