When I said the mobs are RNG I mean they are SUPER RNG, like count of Limbs, what kinda Skin/Fur/Scales they have, pretty much everything is random (or procedurally generated, kinda like No Mans Sky wanted to do it but failed for obvious reasons XD). Though Explosions should not damage the environment as hard as a Creeper does, should be more like a shrapnel grenade or so. And Endermen picking up shit is boring indeed.
And the whole Darkness Spans Mobs thing is garbage too, how the heck are you supposed to make dark buildings if as soon as you dont light it up it becomes infested with everything you can imagine.
I hate spamming Mobs too, because lag is annoying when they are dumb as bread.
