We were only considering putting the bots back. They did cost us A LOT of money, but they also generated a lot of traffic too. Anyway, we haven't decided yet.
But you have to determine the difference between good traffic and bad traffic.
Traffic that results in only players abusing the bots ≠ good traffic.
Same thing with freerolls. The biggest problem is establishing a large enough player base to create an incentive to deposit & play. It's a positive feedback loop for both the recession of traffic and the increase of traffic, both of which plateau at a certain point.
