Wnen it comes to the Duty Finder, I always keep this in mind:

- Expect the worst, hope for the best when playing with randoms.

- If someone is underpreforming, tell them, give them tips on how they can improve. If they wont do this, then either ignore and finish the dungeon or kick them out.

Fun is subjective. Jusr, because someone likes to play as Ice Mage or Thunder Mage (never seen this before, like wtf?), does not mean that their idea of fun should ruin my idea (which is to not carry slackers) of fun. If someone gets kicked, this means that majority of the group agrees that you need to leave.

System works.
