You can also theoretically get around the anti-gang code for a 3v1 by using an invoker, shielding your allies and nuking your allies with AOE instead of the target, but I'm pretty sure they took steps to stop things that were equally as contrived as rescuing your victim for permalag.
The problem of course becomes when it's your default modus operandi, there are plenty of cabals that will let you fight this way if your allies are willing but generally the more willing your allies are to do this the less competent they are at chasing when it fails so it's a wash.
