B&M's are very different. It's a matter of scale - pros are needed to start new games and keep old ones going. Plus, the rake is much bigger in B&M.

But once you've got thousands of players online 24/7 and every variation of the game available on multiple tables, pros aren't really that important.

The problem that Party appears to have is getting new money to deposit and existing customers to continue to deposit. Only money regularly deposited into the system contributes to the rake. In that regards pros contribute very little, so they are 'acceptable but sub optimal customers' as quoted in another post.
