I'm having the same problems. It's a routing issue as I experience a 100% packet drop when it hops to Zayo servers If it doesn't start reading packets within about 10 seconds I end up getting booted out to server screen. Only happens on Darth Malgus though. Not the US servers.
I bought this from the vendor yesterday for my infiltration shadow, and it literally does nothing. Is this a known thing or am I just bugged?
UPDATE: When I logged in today, it works.. go figure.
The third scenario of GF that sucks is when you get instantly kicked from a group because they were trying to get a guildie/friend/etc into their group. You still get the lockout even though you technically didn't quit the group if they kick you right away.
