Prohibit class/job changes inside dungeons

[Tibian]

This is only good for people who only have one job and feel the need to place restrictions on others..

The opposite is incredibly more restricting. New people want to level up and go into positions that they are suited for and want to play. Imagine a poor Monk who has to exclusively level up BLM/WAR just to do CC speed run. That is far more restricting than simply limiting someone who has every class leveled up to one class. That person can fill up any single spot if that is how they enjoy playing. That poor Monk, who has only Monk leveled, has to live with being a Monk.

As it stands now, this is a dangerous path that will severely limit the longevity of the game if new people are forced to level up roughly three or four classes before they can even start end game content.
