>>38607602The problem is that even if GameFreak buffs certain signature moves, they'll most likely get distributed to other pokemon in the following game, if not sooner. For instance, Super Fang was Rattata and Raticate's signature move, but by generation 4, it was distributed more widely than some of the TM moves. Waterfall used to be Goldeen and Seaking's signature move in gen 1 and while it was inferior to Surf, it's a far cry from being an HM and learned by most water types. Sceptile only had Leaf Blade to itself for one generation, as they gave Leaf Blade to a bunch of pokemon even though they also introduced Seed Bomb and distributed it. The only pokemon that get both good and exclusive signature moves are legendaries and some sparse exceptions like Volcarona, though even being a legendary or mythical isn't always enough in cases like Sacred Sword. It's baffling that GameFreak even bothers making these moves when they give it the worst of both worlds- being more exclusive as well as outclassed. Signature abilities also have this to a lesser degree, such as both of Florges' signature abilities going to gen 7 pokemon.
As for buffs, make Fairy Lock give the effects of Imprison in addition to locking the enemy in.
Also I'd buff
