I think gamblers are looking for sites with the lowest house edge and by dropping the house edge, we would be drawing in the target crowd that we should be targeting.
I disagree with your disagreement. There a few big referral whales that have brought in a huge income to us over the years and they continue to advertise and pull in new customers.
I think our turnover numbers compared to the low house edge sites shows that there is a big market for running the site the way we do. Abandoning our successful business model and going to compete in an already overcrowded sector isn't something that's going to happen.
