Yesterday a friend of mine joined us, from an other server but we are in the same guild, for the beta. We was in a group and he dont saw my/our blue dot and vice versa. I had to made a squad with tag up, that he saw me. The dots stay green even when partied up or in squad for everyone not originally on my server.
! you only get correct dot colour for people people originally on your home server ! .
Thats sad, because is a Guild ally BETA and we can play with guildies from others server, BUT we dont see them with blue dots and that's annoying.
