>>47230269Flash, Defog: Both of these fall under the 'use this to see in caves/actually hit things in battle' category. At present there are too few dark caves and foggy chambers in the world of Pokemon for them to become a staple of any player's moveset—unless the game world is willing to accomodate this, there's no need to keep them around.
Whirlpool: Used in a single area of a single game on an obstacle that's almost never found in nature. Draw your own conclusions.
Rock Smash: Similar to Cut, but with the excuse of occasionally finding items or Pokemon while using it. Add more unique encounters from it and give it more functionality than just isolated rocks—Zelda's bombs would be a great source of inspiration.
Waterfall: How many waterfalls does one see on a daily basis? (Yosemite rangers need not answer) Dramatically scaling a waterfall to the Pokemon League certainly seems like a striking image, but the aftertaste of dropping off your HM slave or taking an impromptu trip to the Move Deleter immediately afterwards undercuts the effect far too much to warrant its continued existence.
Dive: Simultaneously one of the best and one of the worst HMs; the best for how much it adds to the world (in its debut generation, at least), the worst for duplicating Surf's type with half the battle utility. I'd let it slide, though, so long as there's enough deep water to explore.
Rock Climb: An HM with unbridled potential that's completely squandered in its only generation. Climbing Pokemon's many cliffs (instead of a handful of marked spaces) could drastically diversify how the player approaches the game world, leading to all sorts of hidden goodies and special areas. Increasing its power and changing its typing could endear it to players even further.
