Local Rock-type Pokemon missing a Rock-type move.
I don't see many talk about the Rock-type. It is generally a beginners tutor type to learn 'problem' solving through gym battles as many regions have them as early gym leaders. However, as something one uses themselves the Rock-type is frankly in many cases awful. You have solid defenses and resist the most common used type used in the first generations in Normal and in the first 2 generations you had stat experience allowing you to bypass some of the problematic issues of most Rock-types.
Then again, you probably only use Geodude the first generations due to its good atk and being a good enough HM slave.
Later the issues of Rock-types become more apparent with the EV system. Bad special defense (usually), weak to a lot of common midgame types and in later gens even early game types like Grass and Water, bad speed, non of your STAB Rock moves hit... the issues pile up.
For in-game there have been successful Rock-types like Geodude, Gen 2 Sudowoodo, Onix when you can evolve it into not a Rock-type, XY Aerodactyl (I cannot believe they let you get such a Pokemon so early with its mega) and BW Archen. The last two really benefit from insane stats, secondary type and evolution. I heard Nacli is pretty good for making Titans salty but that's about it.
Advantages of Rock-types obviously are being able to squash Bugs, Birds, Fire-types, Ice-types (if your moves hit) as well as usually learning good physical coverage options in Fighting and Ground moves like Brickbreak and Earthquake. In practice, things usually don't play out well. Even something like Archeops is probably just gonna do Acrobatic spam.
In general, however, I don't see myself picking up a Rock-type at all. Geodude and Roggenrola (except the trade one in BW2) needs to trade to get its fully potential. Onix... is a tragety. Fossils are either late game, have slow growth or evolve at an unreasonble level. Many of them don't hit their moves. Many of them move last. Pokemon XD Gale of Darkness Larvitar doesn't do any damage and when it is fully evolved Sand Storm turns make the fight a drag and spearking of a drag... Klawf...
How were your experiences with Rock-types?
