You kill any interactions between players in PVP. And once again PVP is 99% of the time PVE. Fighting and raiding are a very, very, very smal part of the game.
I use battlemetrics to chosse a PVP server to play, checking players time on server, etc … Now everyone is called - !
Please stop ruining the game with stupid decisions like this (last ones was ruining trebuchet, bombs and roll …).
