I have to agree with Zaelar on this, I am only 3 boxing and often team up with a couple of my mates... I then always have to ask them to make me leader... not a big deal with friends but in a PUG it could be awkward.

perhaps a toggle to enable or disable team leadership being tied to party leadership.

while removing the party leader dependency it would be useful to build in shared target info. instead of party1target perhaps have a boxer1target which is set through the addon channel.

exposing several shared variables this way would really open up the scriptability for multiboxing.
