It doesn't matter if the new server is named PvE or PvP. Nothing will change.
PvP was damaged heavily from before. By damaged i mean to the point where PvP doesn't even matter for real PvP players anymore. The best player this game had left 6+ months ago.
I havn't played for 4-5 months, just tried 2 CS games recently and compared to the past the PvP is HORRIBLE.
At this point the best thing would be to remove all PvP content from TERA.
It hurts to watch what they did to PvP over time.
