I've been with GSCH since GW2 launched as our main guild (FoW) has been part of that SORC alliance since launch.
4 of us in FoW are looking for something new so we have just started ESO. Looking forward to the GSCH love in that game as I have felt for several years now in GW2. The 4 of us are getting started together on Sunday nights at 8-9pm eastern.
I am not sure yet how guild invites work in ESO. Looks like the account id is @haasdt.
Thanks and I look forward to meeting up with folks in ESO.
