Joining group will kick you out of the game (due to message spam limit for reasons known only to devs) and as a cherry on top it will also kick you out of Cyro all together so you have to wait in que all over again.
Great feature introduced with latest patch, probably it's another performance optimalization feature, good job zos.
I highly recommend for all of those of you who have to low blood pressure.
And for those of you who are not fans of such features, try joining group before getting in cyro. Of course that excludes any lfg in zone, but hey zos doesn't care about you either way so...
