far as I know there is no "Legit" way to do this.

Also be careful, do to radar Mythic has some nice anticheat/hack software similar to warden. If you are to mod the client so you can run more you might get banned.

Regardless, if you figure out how to do it let me know, Id personally love to be able to run 8 myself. I sent in the question to the grab bag 5 times but got no reply.
