We already have the losing players group. I am in that group and been waiting for auto tournaments and/or card prices/sales to pick up to pull me out of it. I am accompanied by many others in the same situation but that's the nature of the game.
I been warning about the, " this is rigged" topics likely to start for awhile. As you pointed out, once they start it will snow ball into something that is uncontrollable and no amount of proof that it isn't rigged will stop the discussion of it. I don't think having buy in games is an issue as long as we are still getting the $100 daily / $1000 weekly freerolls promised. I actually think buy in games to accompany the freerolls is a great idea and helps to replenish the funds that are put aside for creating more games.
