I dunno, I just feel we dont forsee all consequence or possible abuse, just doesn't ring like a good idea. We never intended to be anything close to a pk server anyway. I like @duel, it can be included in a roleplay manner, or just to test build and have fun between friends.
in order to use a multi person duel you must change the command usage slightly.
It's @duel # where # is any number between 2 and I think 30 is the max. It makes a duel for that many players and put you in it by default. You may then invite up to a maximum of # players.
@duel CAN be tweaked to automatically make a max sized duel though, that'd be a little easier to use IMO.
A possible abuse with killable/no delay duel would be that a friend swordy class of yours could provoke you to greatly boost your dmg on mvps, in woe, etc.
Anyways, you still have to LEAVE the duel to target things other then the other duel combatant. And besides, you can still do it with the duel cooldown. The cooldown just prevents you from doing it over and over again every 30 seconds.
if you could abuse @killable with no delay, duel can be abused in the same ways -_- ./swt lol but I get panda's point.. a flaw I could see would be if a player forgets to turn off his @killable and is leveling peacefully then out of nowhere baam dead % - ./pat
