Yes it is really unfortunate, Primedice is having less promotions while Stake is like unstoppable in promotions. I'm checking the dedicated Primedice forum, VIP challenge was stopped on August for a break and now the only available regular promotion is the weekly $800 challenge. A huge difference now between Stake and Primedice almost in everything such as the number of online players. Primedice now has around 400-500 online players daily while Stake has 10-20x more.
PD becomes redundant because Stake has what it has plus a bunch of other features.
The best way to handle this is to redirect players to Stake while still maintaining the domain. Players get bored quickly just with dice and nothing else.
