Regarding new jobs and battles with them, they've maybe felt more fun than the basic game classes or dungeon running.

In normal dungeons, I might not notice what class others players have, as every class simply does damage, with different moves / animations, and the runs are generally easy.

On the new crescent isle, it might've been a bit refreshing and fun, when classes are more different or have more noticeable impact in fights. Perhaps more so, if fights are challenging (7-8 levels higher) and not too easy. For example, when Cannoneer can blind enemies, it's a noticeable and even tide changing effect. Same could be with TM using slow on enemies, and maybe in fewer cases, if Geomancer uses floating ability. I definitely had a thought, that would like to bring cannoneer to some other instances.
