I have been messing around with ai, and asked it to make a "elemental" class, and this is what it came up with. I'm going to need help balancing it, and it needs more abilities, but it's a solid start 

Class Features:

Hit Points:

Hit Dice: 1d8 per Elemental level

Hit Points at 1st Level: 8 + Constitution modifier

Hit Points at Higher Levels: 1d8 (or 5) + Constitution modifier per Elemental level after 1st

Proficiencies:

Armor: None 

Weapons: Simple weapons

Tools: None

Saving Throws: Strength, Constitution

Skills: Choose two from Acrobatics, Animal Handling, Athletics, Insight, Nature, Perception, Survival

Unarmored Defense:

At 1st level, you gain the ability to use your Strength modifier to boost your defense when not wearing armor.

Unarmored Defense: While not wearing armor, your Armor Class is equal to 10 + your Strength modifier + your Dexterity modifier.

Elemental Points:

Starting at 1st level, the Elemental gains a pool of Elemental Points (EP) that they can use to perform special techniques.

Elemental Points per Level: The Elemental starts with 2 EP and gains 2 additional EP at levels 3, 6, 9, 12, 15, and 18.

Restoration of Elemental Points: All expended EP are regained after a long rest.

Elemental Attacks:

These are basic elemental attacks, which require no Elemental Points but increase in potency at certain levels, similar to cantrips. They are all based on Strength for their attack rolls and damage. They count as magical for the purposes of overcoming resistances.

Elemental Mastery:

At level 20, you have reached the pinnacle of your elemental abilities. You can now use each of your four Elemental Attacks (Wind Blast, Earth Shard, Flame Strike, and Water Jet) in one action by expending 2 EP.

Short answer: No. 

Reasons:

(1) Anyone can ask AI the exact same thing if they want such a class so there is no point to making it, no one will ever use it.

(2) The class is also fundamentally flawed so would require a complete rewrite, it would be simpler to start from scratch than "fix" this. 

(3) You are contributing nothing to the class yet I assume you will tell people you made it, so from an ethical point of view, no. 

If you want to make a class, then you should learn the rules and use your own creativity to make it. If you don't want to come up with the class yourself then why are you spending your time making it at all? Go use your time doing something you do enjoy and are interested & passionate about.
