>>18876277Rock resists Fire and Flying, yes. Those are both commonly used types in OU. Those are the only notable types it resists.
It is weak to Water, Ground, Fighting, Steel, and Grass. The first three are very common, Steel is frequently seen as STAB on walls, and Grass isn't actually all that uncommon for coverage due to things like Rotom-W and bulky Water and Ground types.
Mega Punch is still shit in-game. Even Strength is better, due to accuracy, and it's still shit. You start having a point when you get to Body Slam, but even then...
Also, regular Kangaskhan is still awful. Giovanni's Kangaskhan might have been a problem in Gen I, but mechanics and match-ups have changed tremendously since then.
>I was talking about dark/fairy, not ghost/fairyThe assertion I was making is that adding Fairy to any monotype will make it instantly better. Your question would be better phrased as "is Ghost better than Fairy", to which the answer is "It depends".
>rock is offesively superior to dragons.Dragon hasn't really been all that great, offensively. The main draw was being resisted by only one (now two) types, but the real power of the Dragon type comes from high base stats and high-powered coverage moves.
Rock, like Ice, has almost nothing going for it save offense. It's the only type that hits more types for SE than resist it with no type being immune to it. Like Ice-types, Rock moves are commonly given as coverage to Pokemon with better defensive typings. Unlike Ice, though, most Rock-type moves have shit accuracy, making its defensive flaws even more apparent when you're forced to rely on them in the all-too-likely event that your STAB misses at a critical moment.
>>18876318Somehow, Vivillion is sitting somewhere around B+ in the viability ranking thread. Compoundeyes lets it spam Hurricane without Rain, and makes Sleep Powder fairly accurate. This plus Quiver Dance is actually making it a serious threat. Apparently.
