Golems are useles to the player (ok they hawe one use grinding )
So here is a way to make them beter:
After geting a golem you need to give him 5 diferent flowers to tame him.Now he is your golem you can tell him to follow you can tell him to stay and do some patrolling. If you right clik him with a bed he will sit in the bed.
And he has some new atacks he can trow mobs at other mobs ,he can grab a mob and use them to smash other mobs . He can jump ower holes , he can climb walls using his arms.
