Through almost all of my two-week "trial period" with RoH.
Sounds intense, but it really just consists of filling out a questionnaire for the guild leadership to get a feel for the style of player you are...and participating in two of the many guild events that happen most nights.
I've very much enjoyed my time with RoH. I've been a GW2 player since launch...I've left and come back several times over the years. For the longest time, I never wanted to bother with the (perceived) hassle of guilds. But RoH has been super chill and intentional. I have people to WvW, PvP or PvE with, people to chat with, people to just hang around. Love it!
