I will reply with a post from the post you quoted asking "based on what figures?"
So I still think that having to go 220mil overcap for a PE is way way way to much, however 100mil overcap because of what I said above I think is still to low. Even at 120mil overcap for a PE that is still just as much as spys need for 100dex, so split the difference, so PEs currently need 220mil and spys 100mil overcap to get to 260mil and WOC level. So maybe 160mil overcap for a PE (total 200mil).
This is hell of a grind without any progression till the end, and the spys would have an easier time maybe in grinding it due to having access to better equipment, however the spy would still have to be grinding out an extra 60mil for the privilege.
