I'm actually thinking of making this a thread. But I'll post it here for now. Lets imagine the physical-special split never happened. Which pokemon do you think would be nerfed the most badly? Do you think any would get better?
(If you didn't know, the physical-special split is when we got moves that were both physical and special for each type in Gen IV. In Gens I-III, all Fire, Water, Grass, Electric, Psychic, Ice, Dragon and Dark moves were special. All Normal, Fighting, Flying, Poison, Ground, Rock, Bug, Ghost and Steel moves were physical (but Gengar was somehow still really good).
For example, assuming Fairy was a special type (given that it only has one physical move anyway). Azumarill, the fearsome huge power and belly drum sweeper, would have no physical STAB, and would even lose physical knock off. But Alolan Ninetales and Keldeo would gain special STAB priority moves in Ice Shard and Aqua Jet respectively.
