One last thing I just remembered before the event starts.

In the past rare ships including Prinz didn't drop in all enemy formations for easy difficulty, therefore it made farming those ships in easy difficulty rather tedious.

If possible you should first wait for the frontliners to figure out branching rules as well as drops. If Prinz is a drop in later event maps and there are drop pattern restrictions for easy, save your best ships for that map and attempt earlier maps with weaker ships. You will probably not be able to complete those maps in harder difficulties but unless there are some devious branching rules and enemy formations on the map that drops Prinz (if she drops this event!) you should be able to farm said map in medium difficulty with your top ships.

On the other hand harder difficulties will sometimes reward you better equipment. If it is worth to give up those equipments in exchange for a higher chance to get Prinz is something you have to decide yourself.
