Edge the PvE area of the map(northern are) CAN be done without being flagged for PvP its the main daily area for the event. BUT the Southern are is PvP ONLY and will auto flag you for PvP to do the 2 missions down that area. they DO NOT need to be done if you DO NOT want to pvp but you will miss out on bout 600 rep passing them up.
there is no forced PvP in the Northern area of map BUT if you do the Southern area of the map FIRST you will still be PvP flagged when doing the Northern area and will be subject to enemy kills
when entering a auto pvp area you are given a 10second warning that you WILL be flagged for PvP (the 10 second thing)
you WILL be flagged for PvP for 5min after leaving a pvp area, if you do NOT engage in PvP you will lose the flag (the 5min thing)
justification for the Southern PvP thing no its there if you want to do it BUT there are 2 missions that are PvP that grant more Gree rep. you want the rep do em if not then do the Northern area and be non flagged.
I assume the southern area is for those of us that missed the open world pvp days of ilum and this is their redesign for Ilum pvp
