My suggestion is to replace the Easter Metins with the classic Easter Boxes that drop from monsters, similar with Christmas boxes and Anniversary boxes.
I ask this because imo and maybe other people's opinions, killing metins to drop countless types of eggs is not enjoyable, especially because finding metins while 10 other people search in the same map is pretty challenging and then you get a bunch of the same type of eggs and if i remember well there were like 20 types of eggs needed to get a box.
Another way would be to make it similar to Halloween Event, where you get half item from Special Metins and half item from monsters, then everyone is happy to farm the way they like most.
This way is cleaner and nicer.
