We don't need more mobs except with new weird biomes like end update
what mobs should minecraft add next update?

I think the next update will contain long pointy things to stab people when you are going fast.
-_-

maybe a new boss called as an endersent for an end update which is massive with club like hands and can teleport and do big damage with a big forehead and small endermen like eyes

How about, because minecraft has heard so much about wanting an end update, they do a nether update, just for the fans.
maybe a new type of end mobs?
