Alex said, that people will die faster in PvP. So far so good. You can kill people more quickly.
Given the fact that getting oil is now tedious and that you gonna need 525 oil for one epic heavy armor set (350 for a medium set). With the new PvP update you gonna be at risk to lose this grind more easily (maybe within seconds?) So you will need backup armor, e.g. 10 sets of heavy armor and another 10 sets for your thralls. This is 10500 oil or 105000 insects (if you only get unappetizing fish).
I don’t know the crafting time for fishes yet, but if you have like 50 fish traps, you will need 2100 * Crafting_Time_For_One_Fish seconds to craft all these sets. Without insect farming time (which is variable). Let’s assume 60 seconds per fish. This will give a nonstop crafting time for only the oil part of these armors of 35 hours. If you are online maybe 2 hours per day you can get this done in roughly a month.
Then you get offline raided and lose 1 month of oil production in 1-2 hours (if you are alone)
Enjoy playing solo on officials
(I am playing private with 5x harvest and 0.2 craft speed, which makes these changes not as grindy)
