ok I have a fix, it took a little while since I didn't know anything about java programming but after looking through the server files and moving thoughts between players at aion unique i have a way of disabling aggro from mobs while you are in flight or gliding.
only problem is you will have to compile it yourself because if you are using someone elses server pack that means they are compiling and you wont be able to patch your server with the file i have .
since it needs to be compiled and built into the server for it to work. if you want you can go here to his post and get the patch its on the last page.
