Gladiator Mode ( Inspired by Thoth-Amon when my friend told me about "pvp" world bosses. )
Similar to "TDM" but after a certain amount of time a random player on each team is teleported to another part of the map to duel 1v1.(similar to Thoth-Amon)
The winner of the 1v1 earns his team a large amount of points.
Map could be themed like an Arena or Colosseum and could include traps and Npc's that agro you and award points to your team when killed (you fight over NPC Objectives).
Vanity armour for tokens earned from winning games?
