Well this complaint is more about a TM than an issue with the move itself but what the heck was up with Soft-Boiled being a TM in Gen 1? Only 2 Pokemon could learn the move back then and one of them was Mew who was incredibly hard to get.
And why couldn't Exeggcute or Exeggutor learn it when they were egg themed Pokemon themselves?
It gets even weirder when the move became a move tutor move and for some reason Clefairy could then learn it despite not being able to learn it previously in gen 1.
