I really like this script, especially because it is free. It does the job fairly well, but is lacking some options that players might be accustomed to seeing in a premium script.
OP, I think if you could randomize the wing locations so that it changes every now and then, that would be cool. It would also be nice to see some more options for banking efficiency (# sack loads), random AFK times, etc.
Good luck! I think this is a great start for a MLM script, but since it's free it is hard to find anything bad with it.
