Control points should be PvP map with event open once or twice a week that guilds can go on the square and get point each minute they stand on it for an hours. Guild that accumulated most points get access to the treasure chest which give good loot. That would give a meaning to pvp without necessarily dropping all ur hardworked stuff for ransom. (No one like it to drop stuff that take weeks to get its obvious) So only drop skull in PvP and create event for it. I dont think a player would care much to go in a pvp zone if he dont drop worthful stuff.
