Well, I played there for a week or so. There were people on the first 3 days, but right now, the .online shows around 570 online players (most of them afk) and around 1k offline private stores.
TL;DR - you'll never find a RB party (was trying whole morning). There are no epics in the store (again, spamming whole morning to buy and was ready to give 70/90B for zaken / qa)
Also, the DB class seems a bit bugged (most chars need around 30-40 sec to kill in Hellbound, while DB need 3 hits)
