An Army: Rulers of the world

Wouldn't it be terrific (in a good way), if you are playing in survival mode, and then, you see a giant, like a horde, army, with up to 300 mobs, guarding a zombie fortress, that has great loot. But first you have to get into it, and the army, has zombies with zombie horses with spears, some skeletons with skeleton horses, and some charged creepers, that somehow have organized themselves. This would be a great challenge, introducing a new structure, a organized zombie-skeleton-creeper union in this case, and a great opportunity for players to find something more difficult.

However, the arm, may not guard a fortress, just looking for villages to destroy.

My inspiration is the game Days Gone for PS4. If you know it, you will have an idea, for what i am talking about.

I understand if you don't like this idea, this is little off-minecraft, like a mod, but still, sounds like a good idea, for you to develop. I am a big fan, and really would like, if I can, to help, for developing, in my opinion, one of the greatest games in the world.

Thanks, 

Best wishes,
