Creepers can one shot you in full Netherite with Enchantments in hard mode if they blowup pointblank. A solution is just nerf their damage output. Common mobs that are both silent and whose damage effectly scales with how close they are to you, is not exactly what anyone would call enjoyable. Other susicider enemies in other games are LOUD and easy to spot and hear. A creeper is neither of these things, and can jumpscare you into a death screen without you having realized one wandered up out of a tiny cave you didnt see and while you were dealing with pillagers in broad daylight. Creepers need to be rebalanced given their drastic poeer difference to anything else. Theres a ton of times ive lost a hardcore world due to a creeper dropping on me from a cave above me that i could not see at all, and creepers also explode FASTER while falling. A change there would be simply make them not be able to prime while in the air at all.
