after they tested out the no cp for every single campaign, did they comment on anything afterwards? i myself prefer an equalized pvp field were u get to 50, theorycraft your build.. and fight.. instead of using cp points to enhance your needs.
They said in ESO Live that CP calculations didn't actually make as big of an impact on server performance as they had initially thought. So it's likely they will not completely remove CP from all Cyrodiil campaigns. More likely they will keep no-CP to Azura's and battlegrounds.
All they were testing is seeing how much CP calculations impacted server performance. It was merely a means to find information that might lead to a solution to the Cyrodiil performance issues. Never about making all of PvP non-CP,
