The new Mounted Undead are too rare, and too easy!

I've been messing around with the new snapshots and they've been great so far, excluding one thing-- I never see any monsters with the new mounts or spears! To solve this, I think mobs with spears should spawn more often, and horsemen should be more threatening! For the spawning, I think just increasing a hostile mob cap, and making armoured, spear-equipped mobs more common is great. For the AI, I can literally run away from a zombie horseman. Now, to solve that, I think spear-equipped mounted mobs should be made faster, and charge at the player. We get a jab and a charge with the spear as well-- mobs should also use that jab attack. When on foot, that jab should be the default, and when mounted, the charge should be used to rapidly gain ground on players and remove the "sprint invalidation" of everything threatening. Perhaps also, allow Husks to ride Camels and use the dash with a Spear? Now that would be mayhem
