The problem with keeping old threads like this alive for so long is that the original post can easily give incorrect information later on, and most people don't bother to read much after that. I've gone ahead and edited the original post so that we can avoid this issue in the future.
I'm also going to lock this thread because it's 9 months old and there's nothing left to discuss about /follow in Ashran—it doesn't work. So, rather than continue to bump it with mostly irrelevant information, I'm just going to lock it. If anyone has any further questions about Ashran, like how to join the battle or maneuver their characters around in the instanced battle, then please open a new thread.
