"There has been more PVP than ever was in Warz" cant agree at all, there always was enough pvp in WarZ/Infestation, basically every full server had people at clearview.
I also hate the limited space in the global inventory and 45KG per lvl seems waay to low. As molymanade said, thats only a big backpack full of stuff.
You also shouldnt forget that there were a lot of people in ISS / WarZ who loved farming and basically never did PVP.
