You might want to wait until this server launches in a few months. Right now the server is in the beta /level 40 phase. As to your question, population is good, 500+ players daily at peak hours will probably be significantly higher once it launches
This server is currently in beta. It is free. If you want to try it now know that the population is much lower than it will be at launch. I’d say it is between 150-450 people on average. European time zones have the higher end population numbers. Im guessing launch will see around 10x those numbers.
You can /level to 40 currently and instant 50 should be coming “soon”.
