theres all kinds of random difficult enemies in mh but i think something they handle real well from a design perspective is . how different the difficulty scale of an elder dragon is? almost every elder dragon fight in 4u is drastically larger, or stronger, or faster, or has entirely unique attacks to it. & i think that really gives it an impressive feeling of fighting against a being beyond yourself. thats what they should be & i think the way theyre assembled really pulls that off
