Well I guess if you get ganked really if everyone is on top of each other its impossible to really figure out who the heck is the actual leader of the set up. PVP advantage? Easier if its melee to multibox?

And yeah not sure if its possible to do this, the clones can follow the main but being on top of each other will only really work if you have then all facing the same way and on top of each other, but as stated you will get out of sync so not possible to do it very well.
