Giant Zombie less giant yet more challenging.

Here's a thought. Since the Giant Zombie mob would possibly be a impossible entity to hit like the ender dragon at some parts of its boss fight, why not down size it just a bit to make it more viable to be fought with melee or bows? And since it is very, very buffed zombies, wouldn't take make it like their ruler? Here's my idea on this. You're traveling the endless lands of Minecraft till you come across a barren land. It has the muddy blocks of a swamp, with the dead bushes of the harsh desserts. But what comes to your eyes are the vast array of moldy vine covered stone like structures, each nearly resembling grave stones...and then, the chaos insues. The undead start propping out of the graves like how the Warden crawls from beneath the ground to search for who dares make noise around it. Each can be cladded in armour, holding a weapon or toll from their past life, or a bit of both. Hell, maybe some can spawn riding their undead equine companion, the zombie horse. And as you or your friends are fighting the endless onslaught, you hear a low zombie groan and see a slow moving, towering giure getting closer as the zombie swarm dwindles. There, the new mini boss or boss in general has awoken, the Giant Zombie. It dares not to wear any army due to its hulking size, and it can be damaged yet very rarely did it do high amounts of damage. The solution? Splash potion of weakness. Even the playing field and claim your reward over the undead army. The reward I don't know yet.
