The Ender Dragon Zombie seems to take drastically less damage than any other mob, for no apparent reason. I am really hoping some silly damage per hit cap wasn't coded in to artificially increase the mobs difficulty. I didnt see this in the configs to disable either. Can you please let me know if there is in fact a damage per hit cap on the zombies?

the zombie it self is equiped with ender dragon armor

Ok, thats reasonable... thanks! I hate when authors push artificial caps onto mobs. Extra armor is more realistic.
