this is my second one, it works! yet i have be the only one in the overworld lol. still worth it.

it gets on average 20 mobs per drop, although when theres one other person in the OW it gets about 2 or 3 per drop

the last pic was in my creative slab world which gets about 30 mobs per drop, it also has a seperater and mob softener which  i dont plan on making on the server though.

theres these endermen that drop oit of the spawner! i have no idea how cause theres no way that they can spawn. i think it has to do with the slab roof. not sure though, if anyone knows why that would be awesome to know. they take up the mob cap

Looks awesome! What makes them fall through though?

[Underlad]

theres a timer that turns on a dispenser with water to flush them out, then it brings the water back in to make them spawn again.

Ah, ok. That explains it. Pretty awesome design!
