1. GvG or Team based Attack & Defend Maps.
Like Fort Aspenwood except that it's not random.2. Capture the flag maps.
Both teams have a base where the enemy flag is located. Each team must venture into the enemy base to cap the flag and bring it back to their base. The games would be time based and points rewarded per flag cap. 12v12 would be ideal - offensive squad, defensive squad, and mid-field squads.3. Assassination Maps
One team responsible for escorting Guild Lord to Destination location. Other team responsible for stopping them or assassinating the Guild Lord. Could reuse some PvE maps.4. Deathmatch
Using PvE maps, players are randomly scattered around the map. Hunt each other. Last man standing wins.5. Kiting Maps
One team (12 - 16 players) all skills are disabled must reach a defined point. Other team (4 - 8) with skills enabled must stop them. Each time your reach destination, gain points. Game ends after x minutes. Rez at start after death.6. Bragging Rights - not PvP - but a suggestion.
Random, each player given 10 seconds to inflict as much damage on a dummy object. Winner is player that inflicts the most during that time.
