There is a lot of friendly people in eureka here on NA. I would join as many eureka discords as i can people can help answering any questions you have so you have a easier time leveling etc. Ask people for the eureka discord invite links when you are on another datacenter. Dynamis DC eureka is always low activity you have a much better time on Primal, Aether or Crystal.
I can list all the eureka discords for NA
Primal DC: The Help Lines, Agents of Eureka, PEBE and FRAAAG RUN?!?!
Aether DC: ABBA
Crystal DC: CAFE
Dynamis DC: DAFU and DBA
