I still don't really get how it "kills the poker economy" though. You have to realise it also attracts people to play on the site at all, i bet there's plenty of casuals/fishy players who would play poker in hopes of hitting the lotto rather than consistently trying to win.
Furthermore, the majority of tables on any site will always be the normal tables, BBJ tables being ran are usually a relatively small percentage.
And.. as i said before: the edge you get playing on these tables can be quite interesting, i'm sure you can agree here. It really does attract bad players, i see it all the time.
