It's insane that a game with so many character options and 9th level wish spells can't come up with improved wild shape options! so here is a spell I have created. DnD won't let me publish it because it says it's too close to shape change. Thats true but there are many differences. First of all its starts out as a 4th level spell, and still have to use a wild shape charge to even cast it. I think DnD needs to come out with more wild shape items and wild shaping options for druids. 

Monster Shape

You assume the form of a different creature for the duration of wild shape. The new form can be of any creature with a challenge rating equal to your half your druid level (rounded down)or lower. The creature can't be a construct or an undead, and you must have seen the sort of creature at least once. You transform into an average example of that creature, one without any class levels or the Spellcasting trait.

Your game statistics are replaced by the statistics of the chosen creature, though you retain your alignment and Intelligence, Wisdom, and Charisma scores. You also retain all of your skill and saving throw proficiencies, in addition to gaining those of the creature. If the creature has the same proficiency as you and the bonus listed in its statistics is higher than yours, use the creature's bonus in place of yours. You can't use any legendary actions or lair actions of the new form.

You assume the hit points and Hit Dice of the new form. When you revert to your normal form, you return to the number of hit points you had before you transformed. If you revert as a result of dropping to 0 hit points, any excess damage carries over to your normal form. As long as the excess damage doesn't reduce your normal form to 0 hit points, you aren't knocked unconscious.

You retain the benefit of any features from your class, race, or other source and can use them, provided that your new form is physically capable of doing so. You can't use any special senses you have (for example, darkvision) unless your new form also has that sense. You can only speak if the creature can normally speak.

When you transform, you choose whether your equipment falls to the ground, merges into the new form, or is worn by it. Worn equipment functions as normal. The GM determines whether it is practical for the new form to wear a piece of equipment, based on the creature's shape and size. Your equipment doesn't change shape or size to match the new form, and any equipment that the new form can't wear must either fall to the ground or merge into your new form. Equipment that merges has no effect in that state.

For every spell level above 4 increase the CR of the Creature by 2.
