If you do not play for about a week, yes, you miss a lot of the phase/season for that server.

Thank you, always wanted to try that game but was afraid to go into an mmo if it makes u feel u miss alot if u do t play every day

There is a bit of grinding overall and the different servers are locked behind a couple of days of grinding for each phase. After you play a couple of servers though you learn what levels fastest and what to gather, etc.

Is there alot of grinding in the game u need to do?
