Suggestion to make duels less exploitable: At the end of the duel, teleport each player (or just the winning player) back to where they were when they typed /duel or /accept.
SCENARIO:
1. Player A wants to capture the other team's flag. The flag is heavily guarded, with some people defending mid-map and others staying back at the base, including the rookie Player B.
2. Player A challenges Player B to a duel. Player B, clueless, accepts.
3. Player A, now invincible, is able to make his way into the enemy base without any trouble. There he finds Player B, still defending, and explodes him.
4. Player A grabs the flag and takes it back to his team's base for an extremely easy point.
