After more investigation we have found out the reason for constant disconnects while using GB2.
Blizzard added some server side checks to block the usage of a teleport hack recently which may get triggered if you move right after you mount or dismount. There are legit users getting same disconnects as we followed in blizzard forums.
Therefore we have added some waits after mounting to Flightor (flying navigation used by GB2 and AB) to avoid getting disconnected. Hopefully blizzard will notice this issue and improve their server side checks for the teleport hack so that we can return back to faster mounting in GB2.
Note that this change may slow your farming process a bit, but thats the only way right now to avoid the issue.
