What would be the point? With everything being scaled in the next DLC, raising the cap only serves to weaken players currently at 160 and forces everyone to farm mats and the same gear they currently wear just to get back to where they are now. This isn't like other games where new content is higher level and new armor is as well. Unless they intend to do away with scaling then raising the cap is simply a nerf to nearly everyone which only grinding out new mats will fix.
