I think it's the fairest approach to try separate these groups of players, I'm just trying to find the smoothest way to do it. One thing I'm experimenting now with is a special PvP variant of bustabit with high bonuses, starting from 0.9x and being 0% house edge. And to limit the unbounded risk of offering a 0% house edge game, if the net profit is < 0, there will be a small rake. (e.g. if the game loses 20 BTC, there will be a 0.1% rake, or 100 BTC and a 1% rake etc. )
A small rake is foreseen anyway not significant. Maybe Ryan is going to offer this PvP game like an addon to the main game ( traditional one).
If it was at me I wouldn't change a single aspect of the actual bustabit and still don't understand why it is going to be changed: I could be wrong but I guess it is the most successful game in bitcoin gambling industry just the way it is now.
That's my perspective as well, as the old saying goes "it if ain't broke don't fix it"
