yes! bcus they are craftable they arent super rare which wouldnt create an unbalance. a trident is the same as an unenchanted diamond sword but slower, more effective in water and has a longer range. i think mojangs priorities isnt rn to think about adding my suggestion which i will tell in a few seconds but this could make pvp a lot cooler.

number 1 issue is that when you throw the trident with loyalty. your 1 bar fills up if you pick it up and that means the trident will just levitate around you which makes it hard to pvp with. so i suggest when you throw there will be a somekind of barrier block which stops you from picking items after you throw a trident

i agree on a bit of stuff like runes but i dont think sharpness is they key. maby you could disable a shield with a trident which could be nice and give it more purpose. i dont agree it needs sharpness because its already throwable and does dmg. maby a slight increase it having sharp 2-3 but past 4 it will just become too overpowered. i have to say maby not icy as it will probably make crossbows useless. it could have a knockback effect for the blast rune i cant see much of a problem there.
