If you played KOTOR you must know exactly what Im talking about
If you didn't, well I'll explain it here...
The Dueling Ring was part of a quest on Taris where you become Ajuur the Hutt's new fighter under the name of "The Mysterious Stranger" and you had to defeat all the ring fighters in one on one combat to get some credit rewards.
What Im suggesting is that we get a similar kind of dueling ring (maybe on Nar Shadda) as a week event like the Bounty Brooker's event, where people can sign for tournaments that works like a warzone arena but where only the winner gets rewarded with a big amount of credits and comms.
How would it work?:
Place an NPC where the arena should be at (It could even be Jiradda the Hutt or also Baron Deathmark who are already famous on ToR for this kind of games.) when you talk to him he gives you the option to sign for the tournament or leave. When you sign for it you automatically get into a queue (if you leave the queue you of course get removed from the list) and when the tournament list gets full (8 people signs for it) every participant gets a WZ pop and gets into a WZ where everyone starts on an individual forcefield cell placed at the border of a circular arena in a way everyone is facing another player. While everyone gets inside the wz, let the announcer says his words to the spectators and stuff, when the timer for the warzone to start ends. a pair of players facing each other selected at random gets free from their cells and must fight each other to the death. when the combat ends the winner is returned to its cell and let the player who lost to decide to evacuate the warzone or stay to spectate the rest of the fights, (that player is already removed from the tournament list so he's not fighting again), and repeat the process until every pair of players on the warzone have taken their turns. (only 4 players will remain) Let the announcer take a short speech about the remaining combatants and then release two players at random who must fight again (that will leave 3 players left). after that fight, the other two players get released to fight. (leaving only the two finalists) Let the announcer take a little speech again about the final battle and release the remaining players to fight each other (an epic song for when the battle begins would be sweet) when the combat ends the winner gets priced with a big amount of credits and WZ comms and gets locked from participating for today (If you lose. You get nothing but your are still able to sign for the next tournament).
This Dueling Ring event could also have its own Reputation tab, in that case players who lost in the elimination round get the small rep. items, players who lost at the semifinal and final rounds get the medium rep. items and the winner of the tournament gets the large rep. item.
As for the reputation vendors we could get some of the classic outfits used by the ring fighters on KOTOR: Dead Eye Duncan
and the Mandalorian armor of Bendak Starkiller
for Legend rank.
