All jobs having Z6s is a broken OP idea and I don't think it's effective. Last time it was somewhat different as everyone else had something special, too.
If having not enough Z6s is an issue, it seems like a battalion issue of the HVY branch. You need to just get your HVY branch succeeding to get the Z6s like the rest of us. There is no reason a medic would rock a Z6. Just get your HVY branch up and going or make some new formations that don't need that many people.
DU are already pretty strong as is with their shields. A Z6 would push it over the top and make them more OP than the rest of us, I think.
