Thank you for basically saying what I've said all along. lol
Although, you do minimize the luck part when they do not follow a predictable pattern. There's some luck involved when they just shake it up a bit, but it's a flatout crapshoot if they put any thought into it at all. Even then, there is a chance that they can still be caught but it's very slim.
This is why there needs to be some change to the mechanics of dueling, whether it's a cool down, moving duels to the field, or however it happens. It is possible to duel with very little chance of being dueled back, and that qualifies as "broken" in my book. As you say, it's much more likely that the hider gets a little cocky and actually ko's himself on an underestimated opponent. But lets be real here...if they're smart enough to have unpredictable patterns, they're not likely to do that very often.
I still equate the current dueling mechanics with a fighter having the ability to deliver devastating amounts of damage to another player, but a simple door on a closet stops the fighter dead in his tracks. It doesn't jive.
I do agree that 15 minutes is too long...15 minutes total for a duel/hotel queue would be more than sufficient. As in 10 minutes for the duel and a 5 minute cool down, but unfortunately that's not how this poll is set up.
