i think rock is the worst type mostly because it lacks a strong identity. like, bugs and psychics make up for their middling typing by having a lot of standout moves, ice types have incredible offensive prowess that shore up their weak defenses, normal types tend to have enormous movepools, but rock pokemon tend to just feel like half-hearted attempts at making a tank. dreadnaw and coalossal are good recent examples of this, they just kinda dont have much going on in general and their type doesn't help much. i see a lot of complaints about rock moves being inaccurate but IMO it would actually be pretty cool if game freak committed to rock being a high risk high reward type with strong but inaccurate or high investment moves. head smash and meteor beam are good examples of this but i wish there was more
Right now, Rock is literally Ice with a physical bias. Down to the weather defensive buff being the thing supposed to save it, but it hardly helps.
Snow only ended the idea of the best Ice-type being a Water-type with Ice Beam. Now it's Alolatails.
The buff is nice, but when you have to manually set it, and it's 5 turns unless you burn your item slot to turn it to 8? It's not moving the needle.
its funny: despite sr being a worthless move in vgc, i think the rock type is much better there. its not the best but especially on earlier formats rock types can get good results, and they have decent moves to use still like meteor beam, rock slide and wide guard (though this one is learned more by non rocks lol).
Because SR is trash in VGC.
Sneaky Pebble has finally done what Steel couldn't. Make Rock obsolete for good.
Think about it, especially in gens without Boots. Being weak to Rock was a massive hit to a mon's viability, and a 4x weakness was essentially a death sentence.
That made those metas shy away from mons weak to Rock, which made its offensive value go down. What about defense though? Rock has always had very bulky physical mons...
This is what the average Rock mon has to offer. Slow offense with great coverage, but a crippling defensive type, especially since your opponent is usually attacking first. Rock
barely worked as a defensive type in Gen 1 because Steel didn't exist, so it was the premier option for handling Normal offense. It was still very, very exploitable.
Once Steel was introduced though?
Comparing it to Ice makes it look even worse, because you're at least getting good offensive value out of its hits, and they got moves like Aurora Veil, Avalanche, Freeze-Dry, and more importantly, widely-distributed priority in Ice Shard.
Accelerock is a signature move on a mon that's already fast to begin with. Meanwhile, Rock has accuracy issues. The one move that I'd say makes waves would be Head Smash. Head Smash on mons with Rock Head is a nuke button that's pretty much exclusive to Rock-types.
Rock is a strong contender for worst type in the game rn.
The only underpowered type is Psychic. They have some things like psychic noise and future sight, but every other type is better by a decent amount (poison is amazing defensively once you look past the ground weakness and many useful status moves, rock has multiple moves that define metas (stealth rock, rock slide) and good pokemon in said category (tyranitar, garganacl) that use the good attributes of rock).
If you really think about it, psychic is really just something that most mons that have it try to overcome. Really the only mons that like the typing are the fairy/psychic types, and even then stuff like the dark neutrality are a downside.
Psychics are just a victim of the nerfs they took.
They'll never be truly unviable because a lot of them still get to hit hard and fast with their STAB. For example, as lackluster Espeon is in 2025, it's still clicking Psychic or something like it off 130 SpA/110 Spe. That will never be truly bad.
Gen 4 really twisted the knife on them when it comes to competitive viability though. Being weak to Ghost is awful because it's the strongest neutral-type since Steel got nerfed, Dark has been one of the best types in the game since Gen 6 or 7, everything runs Knock Off, and speaking of moves everyone has on their teams, being weak to U-Turn is pretty awful too.
It's been getting some tools to play with, like Expanding Force, Psychic Terrain, Psyshock, and Psychic Noise, but it is what it is, somebody gotta lose in a game. Psychic can definitely make a comeback when GF stops buffing its opps and direct competition. Fairy was awful for Psychic too.
