If they had the motivation or the time to do a proper tournament like L2Revenge used to and is now going to again, then you'd see an influx of players and much better fights.
Setting up an arena in the colliseum.
Putting all participants against their equal class 1v1, first to two wins in each set progresses onto the next fight.
Auto learn allows people to re-log and have skills ready for every fight, keeping it equal.
Disallowing uniques and titanium and +20 weaponry(if they want) is enforcable, keeping it equal-ish. (obviously captain +17 legit is gonna have an advantage over a +3)
Winners can be set to hero via the database, or even i believe assigned noble points so when the period ends at the 1st of the next month, they can claim hero normally. (Perhaps winners should be assigned 50-100 points to get some books also).
To avoid olympiad usage during the month, olympiad HTML can simple be edited disallowing participation.
Anyone think this is no good?
If you disagree, you're a faggot, or a feeder, or shit at the game.
I kept hero for 8months in a row as a gladiator cos no one could beat me 1v1 in a 100% equal fight.
