Eh? WZC is feg in places besides NA?
If you want to take it down easy, get out a high DPs Weapon like vulcans, approach it from behind while it's kiting, and fire away. Usually they take so long trying to get down to the ground that they get hurt alot. Also make sure that you're playing well (as in, running and covering when it spots you and gets ready to shoot). Most WZCs panic when they run out of ammo in Mode 2 and it takes them even longer to shoot you because they need to transform. Take advantage of that.
