Hello. Have a little sometime to discuss.
For thoes interested in Flyhack i can tell that it still works and that there are no clientside checks on it. The only thing you need to do is keep the two firstmost values that reads from the flyhack value frozen.
This prevents the WoW.exe process from "announcing" that you have changed you "stance" via PacketSend() and thereby you are able to fly without being pop'ed.
This offcause looks funny when other people see you because you are not "flying" but rather running in the air...
For your consideration try;
160() force slowfall
240() force levitate
(both requires nCheck to avoid being disced)
